To be honest that’s part of it haha just want to get this long overdue project on the road I had the tune done a few years ago and barely got the car going the 4l60e wasn’t going into 3rd or 4th sometimes it would if I jumped on it tcc would never lock up I couldn’t figure it out and the place that did the tune is no longer around not sure if the problem comes from the gear ratio and wheel size being different than what the tube was for
