Custom tunes and altitudes

[Osiris]

Does anyone know if I were to take my car from San Antonio ( about 0-800 feet above sea level ) to Denver ( 5280 feet above sea level ) will I have any problems with my car being custom tuned?

I have to use 93 octane, and that will cease around the time I get into New Mexico and Colorado, so I figure I'll need to order a new 87 octane tune from Doug, but I'm worried about what the car might do being up in that higher elevation for the two days I'm there.

Maybe I'm worrying too much?

i have the canned tune for my CAI with 91 tune. i took my car from 1100 ft to 8250 ft without any problems. i was there for a few days.

Whether it's a canned, custom or stock tune ? it doesn't make any difference as both elevation and atmospheric conditions are adjusted and compensated exclusively through the MAF sensor...

Might not be a bad idea to get a lower tune, maybe just check with the locals there to make sure you can get 93 all the way. I know around here there is only a handful that are 94 e5 pumps. The highest otherwise is 91.

91 is the highest in Colorado, in New Mexico it only goes to 90.

Its cool though, I've decided to take a truck with me instead and let the pony rest. I just remember reading something somewhere about custom tunes and Denver's high altitude....
