XPDI 04 Stock Engine First step disconnect the battery The Level One Kit opens-up this area of Cluster After SQUARLEY Removing the large MPEM connections Removing the head and Fuel Rail being careful with the components The pump removal After many years of riding and racing, and being a Group of hard-core riders ourselves, we have developed/earned a reputation of delivering on our Performance Claims! Our Level One Kits are specifically designed for the Rotax Power-Plant and the unique qualities of these awesome engines. When used in the Sea-Doo we love to impress and our Level one Kits will deliver a Big Acceleration Gain and Strong Mid-Range plus an added 2-5 MPH depending on your particular set-up. Our Carbureted Version Kits are almost legendary by now. They are Big-Bang for the Buck! Our PPG Exclusive DI Performance Level One Kits give us the ability to remap fuel and ignition parameters that result in performance gains for Direct Injected Sea-Doos that cant be matched. The DI kits offer the same basic gains as the carb units, but still merely sip fuel, with a slight increase in consumption at WOT for extended periods. A truly amazing machine, and design! The DI actually has fewer emissions than most 4-strokes. Our kits are intended for competition usage. The owner bares the responsibility of your local legal compliances, as you do with your Car, Motorcycle, Truck, Etc.   91-93 Octane is required for the BIG-BANG!! The full-on version of the Level One Kit comes with some extra protection. More than stock......The remapping program has built-in code to let the ECU know that the Knock-Sensor is geting ready to start retarding the timing. Before you're unit starts to even loose performance! Much less let it detonate, or anything nasty like that. Every Remapping cost us, so we have to charge a fee to up-grade from Level One "Lite" to Full-On. That is $250.00 to upgrade the MPEM=ECU (same thing). I spent a couple of years and alot of my resurces to make this a reality. The wait, and the endless testing, didn't let me down. I want everyone to that wants to to come and take a ride on one, to doo just that! Come ride the most PURE SPORT Practical and Tactical Sea-Doo built for Aggressive Riding and the Spirited Racer, alike. (if the rules allow*&*%&*!) This was a vision I had about the sport, when everything was getting just to dam big! Most ALL Sport riders have shown a trend to wanting to stop THE WEIGHT!!! (it keeps growing year after year!) Thanks to the people who are running the set-up and we proud to say, ZERO failures including race units. That is Proper R&D. BEAT IT UP, before you pass it on to the consumer and collect their $$. NOT RIGHT TO DO! WAY too much of that been going on in this and related industries for a very long time. We're not perfect, just driven to innovate and we like to go fast AND make it home. Anyone with any doubts of performance claims? A full refund if it does not perform the way we state! HECK and others too, now state!! Thanks for the good words!! 0-60 in less than 4.0, 64-67 mph depending on your set-up. All of the above is meant: "AS APPLIED TO A CORRECTLY AND PROPERLY RUNNING MACHINE THAT IS IN GOOD CONDITION" before mods!! NEVER modify a high-hour and/or a worn unit without the correct rebuild/s being done. You'll just be throwing the money away, for a short, fast ride. Off my soap-box, DI rules for the high desire too go fast and have the finest handling PWC built to date. IMO   GP@PPG
