Alright so i went out to my car a 2000 GP Gt with an Intense tune. After dining out i get into my car and i can tell the power was out because i opened the door and no lights came on. So i popped the hood and disconnected the battery and then reconnected it and the car started. After driving home i noticed the shifts were slower almost like when they were stock. So i decided to see where it shifted at WOT and it went to 6000 Rpms like it usually would with the tune. Did the disconnected battery mess with anything in the tune?
