..and I hate my car! Well really I dont, but heres my dilemma. With only a 3.4 and IPCM (last year) I had run a 14.240 @ 95.88mph (consistant 14.3's). I had the u-bend, stock plugs, 97-98 airbox, 93 octane. Now this time at the track with the mods in my sig, but with a 3.3 pulley and 100 octane, I could only manage a 14.156 @ 97.80mph, and consistant 14.2's. FYI My 60' are always 2.1's.
JET was kind enough to hook up his scanner to my car and let me make a couple runs with it. We noticed that I had high IAT's (120*/130*/140* - hot air intake) until I got down the track and got good air flow. My O2's were pretty good (929) but began running lean (down to about 900?) in the upper rpms/90+mph, and that was where I was starting to get KR. So JET came up with the idea to put on my AFC 1.0 and run the car rich to try to drop the KR (fyi. the cars idle LTFT's were -1.6 with no AFC adjustments). I set the AFC to 104% then made a pass, I had full timing, no KR and my run was a 14.5 @ 95
, I turned down the % to 102, and ran a 14.3 & 97 (unsure of KR if any).
I may be able to post scans later if JET saved them (thanks again!) but I was just curious is the hot air intake really killing my low end as much as I think it is, because higher mph but around the same 1/4 time tells me I have more "high end" power, then "low end" power like before? and why would the car run faster with KR?
