Hi guys,
I have a 2002 mustang GT with a vortech V2-SQ (stock pulley) and an AFM power pipe, it gives me around 9 pounds of boost at its peak. Since I had the kit installed, both P0172 and P0175 codes keep coming back. I did some dataloging using my SCT XCAL 2 (with the idle sequence as described by Joe at trick tuner) and it seem like both LTFT are at 0.75 at idle thus causing the CEL.
I have checked for a vacuum leak but found none, my vacuum at idle is around 17~18 mmHg (stock cam with idle at 800rpms).
The innovate wideband tells me that I'm right at 14.6 (the wideband is installed after the stock cats).
At WOT my car run like a champs and the only other thing I've noticed is the car is hard to start sometime (when cold). I've join 2 SCT log if you want to look at them, the first is idle for 30 sec with 15 sec at 1500rpms, 15 at 2500, 15 at 3500, 30 at idle a quick stab on the gas and 20 sec at idle. The second log is a 15 ~ 119 mph run (done in controled area ).

What's my problem?
