Default 91 vs. 93 octane?
Would I be able to get away with 91 octane? I always run 93, but its getting to be a chore to go so far out of my way for it.

In CA, all we have is 91 (or race gas). We just have to run a little less boost, a little less timing, a little more gas, and change the HG more often.

With the car that is in your sig, I would use at least 93.

2 octane = about 1 pound less boost you should run. At least that is what Corkey Bells says.
