I just got my Audi S4 chipped (GIAC). Shit my baby flies now. Big difference in performance for sure. Now I can hold off insuring my bike for a couple of more weeks.
Best $950 I've spent on my car. extra 50hp and 110 lb of torque!
I definately recommend this for all Audi and VW drivers. Especially if it is turbo charged. Here is the web page to see the preformance gains for your particular car.
It was funny cause I brought my car into a garage to have it chipped and they call the GIAC rep to do it. When I did pick up my car I found out that the guy who does the GIAC chipping locally I went to school with. Dammit I had to pay retail price for my chip. He said if I knew anyone who needed a chip for their car that he would score them a deal if they did it directly with him.
Here is Jarrod's number if anyone needs preformance parts for Audi or VWs. 604-816-2534 or visit his web page www.fusionracing.net Just say Alan sent ya and he'll score you a good deal.
His a good guy. There is also free lifetime upgrades for the chip as well.
