Name is John if there is anyone that could help. I have a 03 chevy cavalier its supercharged i took a supercharger kit off a cobalt and put it on my car. Well i had my car tuned from a guy and i decided to purchase the tuner software so i could learn to tune my own car instead of paying someone. What im needing help on is that my car shuts off at lights and i upgraded to 60 pound injectors. And i was wanting to see if someone could help me with this.
