So you didnt answer my questions and you act like I dont know what we are talking about.
I understand how a mail order tune works, I had one in my Lightning and it sucked ass from JLP. Not every vehicle will run the same on the exact same tune regarless of Ford or GM, it may command the same AF but it may not work out the best for the specific vehicle.
So what i gather from you is Brian shouldnt touch anything LSx powered and IPS is the only place for GM tuning? Or maybe you came into his thread trying to make him look bad only to gain business by attacking another vendor event hough the customer is happy?
As far as I can tell you should just quit yapping and let your business and the cars you roll out speak for themselves, you would be much better off.
