My car has already been tuned, with the current setup with the 4.38 pulley, I am wanting to go to a 4.25 pulley which should give me an additional 2 lbs boost.
What tables do I have to change. I know airflow and fuel, I am not going to do this until I am confident, but for information purposes. Thanks Chris
Mysetup is a 2002 procharged c5 A4
