Customer feedback:

Fred Abrams - 2003-Audi-a6 2.7t

 

Hey everyone my name is Fred and I am new to this sight and I have never done this before. But things worked out so well I have to share this with everyone. I have an Audi A6 2.7T a friend of mine from work suggested if I would like to get a better performance out of my Audi he new some. Well he did and his name is Tony Lawshee from CS Tuning from Chicago, IL what a professional he is in every way. First he came out to my work in Cicero hooked-up his laptop to my car to get information he needed so what I wanted to have done would be flawless. The next day I went to P&L Motorsports to have installed a custom chip tuning, changed all 6 coil packs, changed all 6 plugs with ngk v-power plugs and a new K&N intake air filter and also put my car on a Dynojet. Tony showed me every part he was using what it did where it went and what it will do for my car. Next thing I will do is Piggie Pipes and Diverter Valves. Once again what a pleasure it is working with Tony and CS Tuning.
