The car most likely has issues due to being on the stock map at elevation.

If the intake calibration map is not correct and a tuner makes A/F table changes, the barometric compensation will be out of whack and can be outside the ECU's ability to correct.
Many, many people live in Tahoe and Truckee with aftermarket turbos and were tuned at sea level. They drive hard at elevation and yet their car survives. Let's hear from Kevin Weiss and some of the other guys who were tuned at sea level but live in Tahoe/Truckee. I'm not aware of anyone having elevation issues except maybe Sperry, but that's not a daily driver situation.

You, (Dean), on the otherhand, blew your new motor because you tuned it up here and then drove it hard at a track at sea level without data logging to make sure it was safe.

In my opinion, the OP would be best served by getting tuned by a reputable tuner at sea level and maybe shooting a couple logs from elevation to the tuner to be safe.
