i'm living in the netherlands! The guy that was running the enginehead that i bought already claimed 180 bhp without putting up boost and turbo changes. So i think it's not compleetly true, but i'm running a other turbo and going for a little bit more boost.

Can somebody tell me how they adjust the fuelling?

I think i'm going to wouter bollen racing in the netherlands. He's good know with all the rs and cosworths. He's sometimes quite expencieve, but you pay for what you get
