I got my 03 terminator a couple months ago from a dealer, and it had a switch in the glove box that i had no idea what it was for. i figured it was for a different tune but knew nothing about it until today. I was able to talk to the previous owner and he told me it was for a dry 60hp nitrous shot that was not in the car when i bought it and of course it was on the nitrous tune. I was just wondering how much that would have affected the performance of the car. I plan on headed back to the track soon to get some new times on the correct tune and didnt know if anyone had any thoughts on how much that would help my times.
