I have searched for this, but can't find a thread: Why does the Cobb Stage 1 not put out more power? I have been told that a "chipped" Audi S4 will push ~300 hp with stock exhaust. That's a 50hp increase over stock! I am wondering why the Cobb stage 1 mod will increase hp by only 30. I seem to remember that torque is increased more. The engines in these two cars are similar in displacement (2.5 WRX, 2.7 S4), though the Audi is a twin turbo 6 of course. Can anyone explain this differnence? Thanks!
