I can't bear giving up my 91 tune though and going back to the dreaded stock tune ._.

Then get an 87 custom tune. The 87 custom tune and CAI, on the GT, will yield about 15-18 RWHP over stock. The gains in higher octane are smaller but still decent. I have little doubt the V6 on a custom 87 will still run circles around a stock V6.

Gas prices are around $3.30 here in GA. From what I have read, the prices will continue to rise!! Crazy!!

I am assuming you don't have additional tunes. When I ordered my SCT Xcal3 from Brenspeed, it came with 3 custom tunes. I am able to choose 87-89-91 custom tunes.
