93 is race gas. lol jk out here at least it is. But that would be great if they made a 101 map.

Race gas is bad for O2 sensors and catalytic convertors, so they don't support it is my best guess.

what is the octane of race gas? so much variance (due to mixing) that cobb probably will not release one...

you would be better off custom tuning it, or waiting for the accesstuner.

i doubt you are getting the same gas as we are getting here in salt lake city. no matter what the octane rating is, there are other variables.

like the basic "not all cars are equal" idea. what map works great for the first six months of one model year, may be a ticking time bomb in the other half. that means cobb would have to get thier hands on hundreds of different petrol formulas, and at- least 100 cars of various pruduction strings.

would you rather have that, stage 3, accesstuner, or utec. unfortunatly, cobb is deciding.

the lead in the fuel does not burn and ends up coating the sensor.you can use O2 sensors with leaded gas for short periods to do tuning. just remove the sensors if you are to run everyday.

It wouldn't be much harder to tune for 100 than 91..

no but 91 is a standard gas. you go to the gas station say fill it 91. done.

unless you have a station that sells 100, you'll have to mix and when people mix they make mistakes. if the ecu is tuned for 100 and you only put in 96 and blow your motor, who are the people going to blame? definately not themselves.

Gotta point, but that's when the disclaimer comes into play.
Also, don't most 76 stations sell 5 gal. drums of 100?
