It's on eBay, trying to help a friend order a chip for his 01 a4.
2001 Audi A4 1.8T GIAC Tuned ECU 93 Octane 5 Speed | eBay

Would be glad to hear other peoples thoughts

 

giac is a more user friendly chip meaning they will custom tune to extra mods you have. power gains between tunes are relatively the same so it basically boils down to which one catches your eye first. i'd say go with it unless u have an apr dealer in your area

 

Where I live there is no giac or apr dealers near me. Closest one is 3 hours from me.
