Wouldn't elevation changes have a dramatic effect on how your engine runs? Out we wheel from 3000ft to 10000ft which I suppose is an issue you may not have.
Also a possibility but so far seems to be fine. If anything so far seems to run on the rich side. I won't lie though I prob would have a o2 bung put in my next set of headers I have made and just run a plug in it until needed. I figure there is alot of folks out there that don't like the idea of SD tune but in reality there are alot of people running SD tunes in cars and having great success.
