I bought a 2003 Jetta GLI almost a year ago and now want more power. It's completely stock. Before I just start adding performance parts I wanted to make the motor be able to handle the power instead of eating away at the motor and transmission. My best friend races a Honda hatch and that motor has been blown 3 times. I want to prevent that from happening. What is the best way to tune a motor from the inside out to handle high red lines and really pushing the car?
