I just bought a 2008 GT500 from a guy in east Texas and I was wondering if I needed to have the tune changed to account for the elevation change and 91 octane fuel. (I live in Utah) It has a VMP TVS and a 93 octane tune.
in your SCT parameters you can adjust global spark
Yes I know. But since Justin said to adjust it and didn't send a new tune, it's fair to say its open.
Did you notice an obvious drop in HP going from Texas up here to Utah?
Colorado is just another reason to go turbo.I've driven back and forth from CO to lots of places at lower elevation, and yes there is a difference. I never spend enough time at WOT to really notice, but I can see on the Vac / Boost gauge a serious difference at lower power levels. Hills at home that take zero vacuum / low boost to climb can be done at 10" vacuum in lower elevations.
I still would never move!
