4.2 performance chip
Hi guys
I am thinking of chipping my 03 A6 4.2. I came accross two different chips. One from GIAC and the other from APR. I heard a lot of good results with the GIAC chips. Has anyone have any experience with the APR chip. They claim an additional 40hp. That seems unrealistic. I would appriciate any input you guys can give me.
Thanks
Ramses
