I'm by no means a tuning guru, but I'll offer up my $.02.
I see that you list a miniAFC in your mods. Are you presently using it to skew the MAF? With the HPT I'd think that you'd be able to remove it from the mix.
Where have you done most of your fueling tweaks so far? I'd think that your IFR table would be fine left stock and maybe just some minor adjustments to the upper end of the MAF table to account for the ported TB. Have you lowered your PE enable threshold? Stock is around 45% for RPMs below 4000 and you may benefit from getting into PE sooner. If you edit the PE enable table, don't forget to scale back the PE adder vs TPS table as well (don't want to go too lean when you enter PE). After that, I'd take a closer look at the PE vs. RPM vs. time table. By referencing your scan data (and knowing when and how long you've been running in PE) you can increase fuel delivery for 'problem areas' in your run (this is where scanning the commanded AFR is helpful).
Which timing (high octane) table are you using (stock, DHP,
Intense)? If you are still getting some
KR after the fuel tweaks, you could drop the timing back a degree.
The LTFT's look to vary a bit in your scan (high negatives with light throttle and high positives at WOT). Is this behavior about normal for your car?
One last item to note about the scan, avoid going WOT when the engine is not up to temp (>160). You don't want to risk damaging the engine unnecessarily. The first two WOT runs in the log show no
KR at all, but once the engine temp got above 160, it showed up.
You may also want to add MAF Freq (Hz) to your scanner and maybe commanded AFR.
Hope this info is of some help.
