I hope this will give us all an answer...About 4 weeks back I took the battery out for well over an hour to have it tested because I was having a different issue and I re-installed a new one. Being that the battery was out for over an hour, wouldn't that reset the computer and put the Hypertech tune back to stock? If yes, then the truck still had the lag/pause issue. If not, then I have to literally remove the tune and give it a shot. I guess it wouldn't hurt to try it anyway but the Hypertech takes an eternity to program.

How long does it take to re-program with the Gryphon?
