I recently put a predator tune in my cts-v and right when i i loaded the tune i started the car and the traction control light was illuminated. When i drive the car in first and second gear it stumbles very bad. Seems to be ok in 3rd gear and up. Also every time i start the car the average MPG resets ans the digital speedometer disappears. I thought it was the tune so i loaded the factory tune back into the car but it acts the same. If anyone else has or had this issue any help would be greatly appreciated Thanks
