I called him and even txt some of the problems and at first he would just say well it’s the crushed section on the exhaust or “that’s the tune and it’s done”. After that he just didn’t respond and if I have to ask twice I’m not going to ask again. The guy might know LS motors but not the LTs. Funny thing is their slogan is “we take horse power seriously” well apparently not.

That is just plain awful. You are right, big, big difference tuning the LT4 versus the LS series. Mike at Vengeance told me it is night and day and not remotely comparable. Thank you for posting the name of the first shop. Yikes!!!
