I have a stock 08 RZR and the only mod's so far are 28 inch Mudlites with a two inch lift and snorkled.

I'm looking at adding 30 inch Silverbacks soon and maybe an aftermarket pipe and a clutch kit from EPI.

Which brings me to my question, what is the best fuel contoller for my type of riding which is mainly mud and creeks. Once I started searching the forum for fuel controllers I quickly learned that there are different ones for different types of riding. It looks like PC5 comes up a lot and Dynojet . I'm really not sure what I'm looking for but I want to have options to play with. Mainly I want MORE POWER!!!!:ride:

Thanks for all advise.

Rick, you do realize that you will loose power when you increase the diameter of your new tires right? Remember the RZR is geared for 26" tops.You will probably need to tweek the clutch just to stay close to the acceleration you currently have. I can't help you with the ECU question for when I added my Turbo it came with a secondary ECU,

A fuel controller alone won't give you noticeable power. They are only meant to get your fuel map back to run at a proper AF mixture which changes when you change things. From what i've read on here people arent seeing much power from just an exhaust so i dont think you'll see any significant power from the exhaust and fuel controller.

The PC5 is made by dynojet. With the autotune module it make your rzr's engine work on a closed loop which reads your AF mixture from an O2 sensor you must add and corrects the fuel map on the fly. If i were to put one on thats probably the way i would go. I do know my rzr runs a little on the rich side since i snorkeled it so maybe your AF mixture isnt perfect. The clutching will be much more bang for the buck going to 30's. Unless you dump some major bucks into the motor, dont expect to win any races with those tires and the modifications you mentioned.
