Any Base maps out there for 06' STi with AEM CAI and HKS Hipower exhaust/muffler...i am using Cobb AccessPort V1 ...or would normal stage 1 maps from Cobb be ok ...sorry if dumb question , i'm a N00b

if I recall correctly, the AEM takes a decent bit of scaling to work right on the STIs. In the extreme low range of the MAF curve, the trims were ~10% negative. In the big-end they were approximately 5-10% positive. I usually have to do 2-3 flashes to get the open loop fueling dialed in, and the MAF tool takes care of the low-end. It's a pretty consistent intake as far as laminar airflow over the sensor element goes, but not one of my favorite pieces. Heatsoaks too easily!
