I've worked with both closely and had Pray (Brett) work on a couple of my cars. GPI was great, responsive and they have an actual shop/crew to get work done on a tidy schedule. Their results are incredibly competitive with Pray's. Brett, on the other hand, is perpetually slammed. The poor guy is forever inundated with work but, that's because he's one of the best out there. If you can be patient with him, he will absolutely take your car to whatever level you want and exceed your expectations. He is now working with a shop called Prodigy to get a lot of his in-house work taken care of and he's also hired someone to help take some of the workload of his head porting off of him. So, he's making strides in that department.

Ryan at GPI or Brett at Pray will both have your car screaming and hurting feelings. Neither one of them will remote tune a stock bottom end LT1 w/ boost but, Pray will tune a factory supercharged car if you ask him to.
