Just as it says in the title. I had GIAC on my MKV GTI but no longer have the car and have APR on the TT. Used it only once but never really wanted the stock program again. I can get a picture if necessary.

 

wait wait wait this will work on a tt and its a giac chip for 95?

 

that was ment to be a question

 

Its not actually the chip, its the handheld device that plugs into your OBD port to change between GIAC programs. Like if you had a stock, race, and valet program you could switch between them with this. It looks like the device halfway down on this page.

will it work on other model cars?
