UTEC: What parameters do I change for high altitude and 91 octane?
Hi guys, getting my UTEC this week and I've got a couple of questions...
My Rex is bone stock and this is the first mod I'm doing. I'm in Denver with 91 octane gas, what do I need to modify on the stock map to compensate for these two things? I've never tuned ANYTHING before so please be as specific as you can!
Thanks!

You should per 2 degrees of timing under full boost per point of octane. The TXS cars are tuned on 93, so you are going to want to wipe out 4 degrees of timing. Then get you are good a/f ratio and tune the timing from there.
Hell of a first mod man! You crazy...good luck!
