I have a 2000 GTP in Colorado Springs. It has Thrasher CAI, Speed Daddy headers through stock cat-back (no cat or rear O2), Autolite 104's, Intense tune (may be old, I dont trust it at all), ZZP Modular Pulley setup (currently running 3.6), and a 180* T-stat. I know with these mods and only a 3.6 pulley I should easily be at 0KR. On a hot day with an up to temp engine i am seeing up to 4KR in 1st and 6KR in 2nd!! This is VERY frustrating as I should be able to be running a 3.4 with no KR. I am thinking it is the tune.... it was in the car when I bought it and I dont trust it and think it might be old. I need to know what tune to get or if there is anyone local that could help me out. Thanks guys!
Update: Just went on a run with my Snap-On Ethos scanner with a new GM upstream O2 and found my A/F to be 10.6-10.9 at WOT!!! EEK way rich. I'm going to order a new tune tonight.
