Just checking to see where your cars shift at......I know the computer controls 2 and 3.....I took it out and actually "watched the tach" and it shifted from 1st to 2nd at 4500 rpms.....I manually shifted and took it to 6k....not intentionally..meant to at 5500......lol......I am going to have Don/Rob lock up the stall in 2/3rd on one of the SCT settings just for when I go to the track but just trying to figure the 99/100 mph trap dilemma......friend in the LT1 wants a rematch soon......
