Sorry wrong forum.
I need help!
A friend just gave me a '99 mk4 with the Z18XE engine, I would like to know what is the best way to squeeze as much power from it as possible.
It already has a sports exhaust and I am just about to fit a piper cross open air filter. I would also like to re-map or change the ecu as well.
Can anyone recommend or suggest any ecu's or chips and anything else that I can do to get more power?
