I bought an Edelbrock supercharger from another supplierand it came with Edelbrock's tune. Car ran like crap and Edelbrock said they know it's a software problem and will get to it "some time in the future." Then I was referred to Bryan at FAB9 and after working with my mechanic remotely, Bryan's tune had my car running like a true race car. I can't speak highly enough about the professionalism, attention to detail, attention to customer satisfaction, and of course proper skill in writing a tune matched perfectly with the supercharger. Well done!
