Just thought I would pass the word out. I have a 2001 A4 1.8t and just had it tuned here in Ottawa Canada. So far I have had the tune for about 3 weeks now and all is very well. Defiantly feel the power increase almost no turbo lag and the car is a lot better fuel. Plus I got the handheld unit so i can go back to stock if required....not sure if i am allowed to post the company of the tuning system but I am very impressed with the results.
