No offense, but it really surprises me how many folks don't think or believe that an 87 custom tune is worth running. Yeah, it doesn't quite give as much "punch" of the higher octane tunes but it still is impressive. Considering that a good 87 custom tune is about a 60-80% improvement over stock as compared to a good 93 octane tune, my feeling is that if I can only afford 87 octane, I'm going to run an 87 custom tune with a CAI that'll give me at least 15 RWHP over the stock tune. The Brenspeed and AM 87 combos do that, easy.

We're at $4.29 here in LA for 91 (no 93 here). My SGT came from SAI with the 91 tune. If I didn't have my motorcycle (42 mpg) and had to drive the car every day (17 mpg city average) I would probably buy a tuner to be able to put in 87.
And FWIW, oil prices are determined by the open market, mainly speculators, who are buying future contracts. OPEC just raises or lowers production based on the spot price of crude.

Well the gas I run here in Italy is rated at 95 RON. Not sure if that is exactly 87 octane, but it is the regular gas not the premium. I don't have a tune, so back in the states I'd run 87. I'll be getting a tune in a few months when I'm CONUS again. Most likely I'll run a 91 performance tune.
