Yeah no doubt cali 91 sucks, I am in the same boat. I have to mix 20% E85 just to run S1 Aggressive. A pro tune will optimize the use of ACN 91, since most of COBBs OTS MAPs are tested with 93.
FMIC is a must, with hot temps here in the valley, I average 140 IAT with stock IC. Bay area is cooler though, but prone to more heat stroke with long aggressive driving with stock IC.
