Thanks. That really helps, I lost a race to a good friend because of this issue. He has 20 more hp than I do in his 5.0, it happened to me 3 runs in a row, he has heavier wheels(big) So I pulled right off the bat one run got the jump and tried to go into 3rd at the last second before limiter to win and there was a full second I was stuck and then the power drops back down and it took another second to get back up, obviously then I was behind him for the next two gears, so frustrated. I only have bama sct tune and shelby axle back. 3.73
