Hey guys, I'm from Las Vegas and I'm going to school in Southern Utah. The elevation change is from about 2,000ft to 6,000ft. When I'm in the lower elevation, my truck runs 200% better. It will spin the tires for as long as I want. But up at school, If I hammer the throttle at low mph, or even sometimes at a standstill, it has a very hard time breaking the tires loose. Why would it have such an effect on performance?
408 Iron Block
LS3 Top End
231/239 114
4L80E 3.42 gears
I can post the tune later today. Thanks for your help
