suggestions for proper upgrade path for high altitude..

Neel V. @Apex can definitely get you situated with a virtually plug & play ViPEC V44 or V88 (depending on your options) and it still maintains your OBC functions. Or you can walk the darkside and try MegaSquirt3, Brendan has helped me a ton.

rock on Rich. My tuner buddy loves the ViPEC. Although pricey, it seems like the best solution for the direction I am going.

Interesting, I run a turner chip on my E28 M5.

Turner does have several chips. I know of a 2.5 Chip, and a 2.3 chip, with the 2.3 being the same as the JC Race . The 2.3 chip has pretty advanced timing and requires high octane fuel (I'm not sure how high though....) The 2.5 chip is more "street friendly" and I'm not sure if there's another beyond that.
