alright, I have a 04 silverados ss with a 160 thermostat, cai and exhaust and 4.10's. I live in denver so my elevation is 5400 ft. My family and I were in memphis this year for the lsx shootout and there is when i decided to get a hp tuner rather than a mail order tune. so i got the hpt a few days ago and i am overwelmed. where do i begin? is it possible to get the truck to run like it did at sea level or better up here at mile high elevation? any suggestions are greatly appreaciated...... oh yeah, nice to be on here and kinda meet you guys! shane
