I'm wanting to bring my Mach 1 up from Louisiana to Colorado this winter(trailered of course). Just curious if I will need to get it re-tuned for this altitude, a little over 5000ft vs. La's 10ft. It could probably use a re-tune anyway to replace the crap tune that gets 12mpg thats on there, but if I don't have to spend the $400-600, I don't want to. Thanks for the help.
