| I have a 2002 330i. With only AA exhaust, I had 182.8hp to the wheels (temperature was about 65 degrees). With ECIS intake, RE pullies, AA chip and the same exhaust, I put out 187.7hp to the wheels. Both dynos were at Eurospeed Performance with their Dynapack.
So, I gained less than 5 hp to the wheels, but on the second dyno, the temperature was about 95 degrees. Thirty degrees makes a huge difference.
