Scott, do you think the problem could be that you're getting tuned at sea level and when you run up here, things get a little lean? When Ed retuned my car up here recently, he mentioned that if anything, my car will run rich at sea level, it seems the inverse would be true for you. You do any datalogging (including AFR's) up here?

Ed admitted to me that there are some maps that Cobb hasn't unlocked, that would allow better control over how the ECU controls things at different elevations...there's only so much a tuner can do, even if they know how to tune a car for different elevations. Basically it seems safer for a car to be tuned at the highest elevation it will be run at (regardless of the elevation is like octane thing).
