03 Z06 Tune issues , logs attached

Looking for some advice from those more experienced than me. This tune is currently in my car, I've never really been happy with the drive-ability of the car, made good power on the dyno but that's just half the battle.
I bought HP tuners a few months ago and started researching. Looking at the tune with my untrained eye I've seen a couple things I don't like, namely the copy and pasted high and low timing tables, the MAF output vs frequency in the 3250 to 3500 range and the misfire enable parameter at max temp.
The car has a surge at low loads between 1800-2200 and high idle at cold start. I've got some paralysis by analysis and would love some help.
Mods are as follows, A&A supercharger, blower cam .581/.588 lift 220/228 duration 116 lsa, ARH 1 7/8 headers, VMAX ported throttle body, Alky controls Meth.

Thanks.
