So...just like many other people with a Stillen supercharger kit using one of their tunes, my car never really ran properly since being installed last year.
I spent a lot of time looking for a solution and finally contacted Vince at R/T Tuning earlier this year to discuss my issues. When we spoke on the telephone, his knowledge inspired a lot of confidence in his ability to sort out the problems unlike other guys that I talked to previously. So it was just a matter of finding time to get down to Pennsylvania from where I live which is about 7-8 hour drive.
I finally made it down there this past Monday and I couldn't be happier with the results. The car drives exactly like stock and was still getting over 800kms highway.
Here are some of the specs on my car.
-Stillen supercharger kit 9psi
-Akrapovic cat back
-Invidia test pipes (had to get installed at R/T because my FI high flow cats were falling apart)
-It was 90-95F degrees that afternoon.
I would highly recommend anyone in the upper east USA or Canada to see Vince for any of their tuning needs.
