Any motor you put in there you will lose power compared to what it would do at sea level. I would boost. If you have the money gsr THEN boost!

Yes I agree...guess not much i can do but boost it. This is my first Vtec motor so im still learning. Good news is its still an even playing field up here because everyone's motor runs the same. Somewhere I heard that if you unplug ecu overnight and replug in the morning over a period of a couple of weeks then the ecu will adjust to less oxygen in air? I dunno. Any truth to this possibly? Thanks again.

You're talking about resetting the ECU by unplugging the negative terminal of your battery. It does not need to be done overnight. And yes, it will allow the computer to adjust to the new atmosphere, but so will driving around for a few days. It doesn't matter, though, because you still won't regain any power. Higher altitude = less oxygen for your motor = less horsepower. Nothing you can do about it unless you force more air into your motor through a blower or turbo. Or you could move back to TX. . . .

yup, forced induction or lower altitude is your only way.
