looking for a little tech help... first i have a 2004 grand prix gt (all stock at this point) and was looking at maybe putting a "chip" or after market ecm in it to have a little more power or atleast more mileage. the reason i ask is apparently the 04 model had an issue with there being a slight delay in the throttle response caused by the computer i was told. it is the "drive by wire" electronically controlled throttle system. its about the only thing i dont like about the newer models. i was told that i need the the computer reflashed but if im going to spend the cash would it be better to just get a tuned ecm or somthing of the nature?also dont want anything thats too over the top that will damage the car or shorten the 3800's life span. any insight would be great! thanks
