I have a customer who has attempted his own programming with hp tunner and cant get it to run (2008 ly6 6.0 in a custom car). When i read the ecm with efilive it says that the vats patch has not been applied. Will efilive recognize when hp tuners has applied the vats patch? The customer tells me that he is sure he applied the patch but i am seeing different. I just wanted to know before i burn a license on his pcm.
One other question, is it possible to disable the VVT on this engine/ECM?
Thanks
