Just bought a 2002 GPGT for a daily, no rust!
so far:
oil/filter
trans/filter
o2 sensor
plugs/wires

I scanned it today for the first time and saw 10* KR @3940RPM (WOT). the car is 100% stock other than some stupid K&N filter the last owner put on it. The plugs I used are AC Delco Platinum

I think I might do a power log and 2.5 inch ZZP DP then start playing with the tune.
