Just want to mention that I got a stage 2 e-tune with Dave. He has been wonderful to work with and very knowledgeable. He has been very understanding of my busy schedule. My car is running like a champ, has smooth power delivery, and as an added bonus has been getting way better gas mileage than it ever has. Will be coming back when it’s time for a bigger turbo and intercooler. Don’t hesitate, this has been the best modification so far.
