- **Note 2021 models have a different helix design and only come with the S2 clutch kit for now** Price difference for years reflects this.
- Lock & Load! This Stage 2 kit provides a big increase in horsepower and torque simplified into an easy package. Tuning, clutching and exhaust on the PXP go together like high powered rifles and tannerite. Together they pack a huge punch for the ultimate power gains to the wheels. The tuning allows for great power depending on the level tune, supporting mods & fuel you want to run. We change boost, timing and hundreds of parameters to deliver safe, yet big horsepower gains. The exhaust greatly reduces back pressure so we can run more boost, and that boost delivers more power. The clutching then transfers that power and turns it into wheel power instead of simply just turning it into RPM. To make sure your airflow is not cut off, we also include our pre airbox intake tube. Since the stock BOV is weak, we include our high quality billet one in this kit as well. This kit is normally/best paired with our level 2 or 3 tune.
- Kit Includes: PV3 Tuner, S3 Clutch Kit, Clutch Limiter, Pre Airbox Intake Tube Billet BOV, Exhaust.
- Clutch kit includes setup guideline that lets you know how to setup your weights for tire size & tune level (Works with 29" - 33" Tires)
- Quicker throttle response and power delivery
- Throttle by wire limiters disabled
- Fan on/off at 185 degrees Fahrenheit (Stock is 190). The fan also ramps up in power quicker to keep you running cool.
- Optional start in any gear! Does not need to be in park to start. Will start without brake, but may throw a code. Press brake to start until we figure this issue out. Keep in mind this is removing a safety feature.
- Seat belt limiter disabled
- Speed limiter removed in low and high gears
- More throttle % and boost in low gear and reverse
- Rev limit at a safe 9300 RPM
- See how to install and use the tuner in this VIDEO
- No mess of having to send in your ECU & this device is a much safer way of programming. Simply plug in to your Diagnostic port, click tune, wait, and go ride!
- Very easy to use tuner that can also check and erase most trouble codes
- Easily data log 32 parameters with 1 push of a button and review on your windows computer later
- Tuner is updated with the latest firmware to make sure you have a smooth tuning process
- 1 Tune (along with your stock tune) are included in the initial price. Additional tunes are $50 each. We highly recommend 2 tunes so if poor fuel quality is an issue you can switch to a lower HP level.
- For reference; a Stock machine will dyno at 156-158 rear wheel horsepower, 181 crank HP per factory
- Tune levels 1-4 are developed on the stock wastegate setting with stock injectors. Tunes 5 & 6 are only available with our 1200cc injectors & require adjusting your wastegate rod. We also offer all tune Levels 1 through 6 designed for the 1200cc injectors & WG rod adjustment.
- The Level 1 tune is a modified stock power level tune but has better boost maps to help keep you in the power. We disable many limiters, raise the speed limit, rev limit, and make necessary fuel & timing changes. We maintain the max factory boost of 16.5-17 PSI.
- The Level 2 tune offers 17.5-18 PSI of boost with a 10-12 RWHP gain. This tune rips and can be used on a bone stock RZR in most cases. We highly recommend our billet blow-off/diverter valve and pre airbox intake tube. While not required, clutching helps transfer the power to the wheels much more efficiently. This tune can also be used with exhaust, charge tube, and intake tube.... etc. No wastegate adjustment required. 91-93 Octane tune.
- The Level 3 tune is a game changer! Hitting hard with a gain of 20-25 RWHP, this tune offers the highest boost possible (18.5-19 PSI) on 91-93 octane fuel. Due to the upgraded Pro XP turbo with higher exhaust flow and more efficient compressor housing, we can get away with higher boost on pump gas. These are absolutely huge power gains that will have you grinning from ear to ear. This tune is built to be a max tune on 91-93 octane. If you only have access to 91 octane and fuel quality is poor or you'll be running really hard that day, we'd suggest using a small amount of race gas or octane boost to bump your octane. This helps prevent engine knock which causes the ECU to retard your timing curve resulting in a slight power loss. Required Mods: High flow pre airbox intake tube, exhaust, Billet BOV, S3 Clutch Kit. Suggested Mod: Charge Tube as we have seen them fail on this level. No wastegate adjustment required.
- Level 4 - Beast mode - 200 RWHP! This tune is designed for 98-100 octane (will run on UTV 96, or most fuels up to 110 octane) and was developed using one can of VP Octanium to a tank of fuel. Mixing other race fuel with the tune to get 100 octane output would work great, just keep in mind consistently using leaded fuels can result in premature failure of O2 sensors. Now for the fun part.... this tune is INSANE and brings your Pro XP to a new level at 197-200 RWHP on our dyno. This tune gains 40-43 RWHP and pushes the boost level to 23-24 PSI peak before settling at 22-23 PSI. Keep in mind the Power Vision boost only reads to 22-23 PSI (depending on your altitude) so it will be close to maxing out the gauge. The ECU still has vision above that, but you won't be able to read it without a manual gauge. Required Mods: High flow pre airbox intake tube, exhaust, Charge Tube, Billet BOV, S3 Clutch Kit. Suggested mod: After airbox intake tube WITH catch can, torque head bolts tighter with 120 degrees more rotation. No wastegate adjustment required.
- Level 5 1200cc Injectors, Waste Gate Rod Shortened - Beast mode times x2 - 210 RWHP! This tune is designed for 108-110 octane Now for the fun part.... this tune is INSANE and brings your Pro XP to a new level at 210 rear wheel hp on our dyno. This tune gains 50-55rwhp on pushes the boost level to 24-25psi peak, then settles to 23-24psi. Keep in mind the powervision boost only reads to 22-23psi (depending on your altitude) so it will be close to maxing out the gauge. The ECU still has vision above that, but you won't without a manual gauge. There are a few other problems with this tune.... the speedometer struggles keep up with the wicked acceleration, and the tires won't stop burning off. Required Mods: High flow pre airbox intake tube, exhaust, Intake tube with catch can, Charge Tube, Billet BOV, S3 Clutch Kit. This requires shortening your wastegate rod as short as possible to 6.5-7psi crack pressure. Also requires torquing head bolts tighter with 120 degrees more rotation.
- Level 6 1200cc Injectors, Waste Gate Rod Shortened - Beast mode x3 - 215 RWHP! This tune is designed for E85 fuel. Now for the fun part.... this tune is simply stupid and brings your Pro XP to a new level at 215 rear wheel hp on our dyno. This tune gains 55-60rwhp on pushes the boost level to 24-25psi peak, then settles to 23-24psi. Keep in mind the powervision boost only reads to 22-23psi (depending on your altitude) so it will be close to maxing out the gauge. The ECU still has vision above that, but you won't without a manual gauge. There are a few other problems with this tune.... the speedometer struggles keep up with the wicked acceleration, and the tires won't stop burning off. Required Mods: High flow pre airbox intake tube, exhaust, Intake tube with catch can, Charge Tube, Billet BOV, S3 Clutch Kit. This requires shortening your wastegate rod as short as possible to 6.5-7psi crack pressure. Also requires torquing head bolts tighter with 120 degrees more rotation.
- Max boost levels are listed as reference only. Altitude, temperature, charge temps, intercooler temps and many other conditions play into a factor of final boost output. AA tunes do a better job of making sure you reach these levels as the factory tunes are overly safe.

This Bites
Size: Large, Size: Large
We've happily used OxyFresh pet water additive for probably around 15 years. I love that product, so I figured their toys would be great too. Not so much. The concept seems good. This does feel like a heavy duty rubber and it feels like a sturdy construction, but in actuality, it did not hold up. Without a goal like food in it, my two dogs had 0 interest in this. It says you can put a treat in it. I wrestled to put a piece of kibble in the jaws of this toy, but that was tough and there isn't much room in there. That did pique their interest. Both my boys are about 50 lbs. One is a heavy chewer and the other is pretty gentle mouthed with toys. BOTH dogs were taking chunks out of this immediately. I must say that I'm really disappointed. If the rubber held up, this is a fantastic concept and seemed like it would work very well to clean teeth. Unfortunately for us, this was an expensive toy that began to fail within about 15 minutes of what seemed to be very average use. We'll be continuing to use a toothbrush instead.

Truly Chew Proof (so far)
Size: Yellow
My dog loves this corn thing (he is 1 year old and roughly 50 lbs). He has gotten to be an aggressive chewer, but this has been one of the only toys that has kept up after long use (4 months since I bought it) and not been destroyed in minutes. There is a nice squeak to it, and I really have to press hard to get it going, but it is easy for him to do it. It is easy to clean, too, because it is rubber.
My only comment is for owner awareness: the description says "good for teeth and keeps them clean". This is false. I believe no dog toy or kibble will "clean" their teeth. You, the owner, just have to keep up with their oral hygiene through brushing. As for the other claims -- the training, weight management, and preventing chewing furniture -- again, use your best judgment. I did not purchase the toy for those claims. But as a durable chew toy, this yellow corn does the job and satisfies the natural instinct to chew.
Note: Some of the negative reviews for durability are for the alternative blue rubber bone, which I did not purchase.

The best chew, play and teeth cleaning toy
Size: Blue
I have a 24 lb medium australian labradoodle multigen. She loves to chew and nothing soothed her teething like this toy. It also cleans the adult teeth that came in. So win win. The squeakers didn't last but that was my fault for squeaking it to tire her out in play. We personally love this toy and will purchase it again when it wears out. So thanks for a great product. 😉

Not indestructible, but pretty close!
Size: Yellow, Size: Yellow
I adopted a pit mix a little over a month ago, and so far he's managed to destroy every single toy he's had, including ones meant for aggressive chewers. He's a sucker for a good squeaky toy, and this had good reviews (and was affordable) so I decided to check it out.
He's had his corn for a week now, and surprisingly, it's still holding up pretty well - though there are some caveats to that.
My boy didn't even want to wait for me to take his corn out of the plastic bag, he too excited to get it. He went to town immediately, to the point where he was sitting in a puddle of his own drool after about an hour. He managed to squeak it (which I couldn't do myself), but still hasn't really gotten the hang of doing so - and the squeaker, when wet, does sound a little... Well, wet.
He managed to have bite marks in it within the first six hours. Within a day, there were tiny bits of yellow rubber starting to appear anywhere that he played with this toy. A week later and there are some decent sized chunks missing from the corn - some of which I've had to cut off when they got loose and I worried about him choking on them.
He loves his corn cob, and will likely get at least a few more weeks of play out of it before I have to toss it for his safety. I'm unsure of whether the squeaker is still functional, but he seems to love it whether or not it squeaks.
Overall, it's not a bad toy for most aggressive chewers, but it will not last forever. The rubber is as heavy as the regular red Kong toys, but it feels slightly softer, which might contribute to his ability to break off little pieces.
Make sure you keep an eye on your dog with this toy, or with any other, especially if they are chew goblins. But I'd definitely buy this toy again.
