NO........ its not what you thought it was sorry!

Anyways.... I Just bought a 2002 GTI 1.8T on last sunday. I need to know what is the best chip for the car? Ive heard some different opinions and would like to get a good idea of which way I want to go. I only want go fast modifications right now. Suspension upgrades will come later. Thanks in advance for any replies!!!
