Usually I've seen 20-22% on a manual and around 25% on an auto.

Somebody that had a stock dyno done can verify but the ones I saw were anywhere from 220-230rwhp.

I got 379rwhp on my TN ST.

 

Any other mods with your set up? It seems that aftermarlet plenums and spacers do well with the turbo. I have the MD 5/16 spacer kit on my set up. Wow, at 20% loss that is about 475HP at the crank. Very Nice.

 

good sh.. man have fun w/ it.. just be careful and "try" not to up the boost too much.. and im sure your gonna say its enuf.. but in time you will attempt turn the wick up a bit..

 

+1^ I think that's a fair estimate on the whole deal. A lot of people forget about tuning, gauges, plugs, etc. From all the research I did that's about what I expected for everything done the RIGHT way. Sure you can skimp on the tune with some kits and all the other parts and pieces but it will only be a matter of time before the problems arise. Regardless of what FI anyone goes with go by the old standard...do it right the first time! My 2psi
