Has anyone had any experience with using performance chips from "GForce" (http://www.gfchips.com) on a regularly aspirated Audi A6 (3.0 liter V6)?
1) ease of installation?
2) how much actual horsepower improvement?
3) how much actual gas mileage improvement?
4) any other issues/comments/suggestions?
I recently bought one of their chips for my 2003 Audi A6 Avant, but haven't had the time to install it yet, so I was wondering if anyone out there would care to share their real-life experience with this product.
