Took the old grand prix to cordova last saturday. It ran a best of 15.58 @ 86.78 mph and a slowest of 15.65 @ 86 mph. The only mods i have are muffler deletes, and a home made cold air intake. i did take the headlight out. i was impressed with its performance at the track for 151,000 miles on it. And that was before i tuned it up last night. This car really woke up after the tune up. Its a totally different car with the TR55s and new wires. Im going to take it out this saturday again ad see what i get out of her. I didnt think it was too bad of a time. I will upload pics of my car tonight and post them.
