Tuning possible on e46?
I own a 2002 330ci with a stage 1 turbo that was installed by the previous owner. I was looking to get it dyno'd and tuned, but was told by another e46 owner that tuning as far as air and fuel mixture wasn't possible on our cars.... This can't be true right
If its possible do any of you guys know of any places in SoCal that specialize in this?
