I had the computer reprogrammed(Dinan). There is a definite improvement. The best phrase I can think of is the car is "frisker".
BMW of Seattle did it. No Warranty problems.
: Has anyone have experience with the Dinan Engine Performance Enhancement Software and High Flow Cold Air Intake systems for the 328i( E46 Platform)? It cost ~ $1000 and claims to significantly increase performance at lower RPMs/partial throttle.
