Well, let's just say the Stillen provided ecu tunes aren't worth mentioning
All i can really say about them is i had to wait for the 7th or 8th tune before the car was driveable. At that point i drove the car to Horsepower Logic
So yes, my car is custom tuned. And by the way, it was custom tuned by Horsepower Logic, the same place RCZ had his tuned. The only difference between his car and mine is that he has headers whereas i have stock headers. I did communicate with RCZ and confirmed his setup.
