I know that the PC3 with hub and a GM map senser you can adj for boost for more fuel. I am in your same boat. I have a buddy that builds exhaust and turbos for cars. But he doesnt do the dyno and tuning part. Thats what im at as well. But from what I have read on turbos. Is to get the crank pinned and welded. But if you have the motor apart then why not throw some low compression pistons in and add more boost.

 

X2 on the crank & pistons, and yes the PCV with autotune works on an 08 RZR...Quadnkev uses one on his, maybe he has a 2009 RZR S ECU. PM him and find out.
I use the PC V with autotune on my turboed 2008, but it has a 2009 RZR S motor & ECU with 2010 internals and CP 8.5:1 pistons in it....confused yet? :rofl3:
By the way it works great for me!

 

yes, the PC5 and autotune works on the 08 too.

 

So how does the PCV see/read boost?

 

Thanks for the info guys. So the pc5 with autotune will work on a stock 08 ecu? That would be great if it did. Would it be necessary to weld/pin the crank if i stay to 5-7psi? I'll probably eventually go with some low compression pistons, but for the time being i'll stay low boost.

grmeyer-Could be wrong but from my understanding you have a choice/option of getting a 2 or 3 bar MAP sensor with the PC5.

 

richochet racings aem system the best ,more h.p. and better fuel milage than any other system plus lots of tuning /saftey/programming features

 

Where are you guys buying your bigger injectors?

 

I'm sill confused on this issue myself, but imassuming just a power commander and auto tune is all you need??? it will do the rest did i read this all right? or what.
