dumb question for you tuners
I have a 93 octane tune from Brenspeed loaded. Works great. But I drove from Dallas, which is 400' above sea level to El Paso, which is 4000'. I'm finding that in El Paso, they have 91 octane gas, but not 93. So, while I'm here, should I load the 91 tune, or will the 93 tune be close enough as long as I keep my foot out of it?
