Why not just unplug the knock sensor and turn the boost up??? and what turbo are they using on that graph.. because you'll said the turbo is a bottle neck.. so if its a bottleneck to flow how do you know when you are sacraficing too much heat for 1psi of boost??? if you go over 25psi on a t3 .63/.60 the gains of boost are goin to be out run by the heat produced.. Ive also heard this as being *crap* air.. just over heated to where there is barely any oxygen.. so it might not be the engine, and the small turbo???

Are these forged internals.. or how do you run 20psi on them???
