I have a 2006 Yamaha warrior stock except some crappy drag pipe exhaust a previous owner put on, and the AIS delete done. This thing fits easily and installs fast, I found the stock settings were so so at best, I had to back off the throttle tip in pot and run the unit at 2-2 and about 1/2 and the bike seems mostly happy I have endlessly adjusted it and my hesitation at WOT is much better but not gone, if I turn it up more it gets worse turn it down to 1 or zero worse 2-2 and 1/2 = best. I wish I had just ponied up and got a USBIII or V Power commander though instead of trying this. I may later on get a PWR Commander and will for sure be getting a V&H pro pipe for it this winter. I don't recommend this just get a Power Commander they are better.

I had a 2007 R1 with a power commander 5 Graves full race exhaust and professionally tuned. And, you know those bikes only make a hundred and forty-nine horsepower stock mine was tuned to 172.8 the bad is R1 in the Midwest... Better ask somebody.

Install on my Yamaha Stratoliner was very easy, took less than 30 minutes. Luckily the tuner for my bike uses a 6 pin connector and not the injector connectors- so many seem to have a problem. Operation and tuning is easy. No PC needed and you can tune any time you want, even on the fly if you were to mount it where you can operate it while riding. That's not happening with a power commander! My bike runs much smoother and crisper now, throttle modulation is smooth and predictable. Fueling is much improved over stock. I have owned this tuner for about a month now and no regrets. Its exactly what my bike needed. *IMPORTANT* The Wiseco instructions for my bike are generic and not bike specific and neglect to tell you to disconnect the 02 sensor, which you SHOULD do. The Dobeck Performance web site (they make this tuner for Wiseco) is MUCH better for install and tuning info.

The Z-FI made a pretty significant improvement in power. Its a lot smoother Then PC5

I installed this kit on my sons Polaris Sportsman 300 and what a difference it made.. The factory setting was so rich the unit wouldn't run past half throttle.. I installed this kit in about 2 hrs due to the fact that I had to remove half the plastics to get the carb off. I installed a Uni filter with this kit and now the ATV will pull right up to max RPM without any hesitation.
