Just looking for some user experience. I have been emailing Justin with my questions but some end user experience first hand would be great.
This is for my completely stock '01 Yukon XL.
I live in Colorado at a minimum elevation of 5000ft and travel into the Rocky Mountains up to 12,500ft. Most of the climbs also include long, steep grades. Does anyone else live up at high altitude? If so, did you go with a standard tune or a data log tune? I'm just trying to decide if the standard tune is good enough considering my elevation.
My second issue revolves around emissions. Colorado has a very strict emission testing procedure that involves testing the vehicles under load using a dyno. With a tune has anyone had issues passing emissions? I am considering keeping my stock PCM, just for emissions, but it would be great to save that $$ if possible. So any experience here would also be appreciated.
