Wife's sled is 2007 Summit with a 600SDI. Going from 2000' to 8-12,000' elevation. Do I need to go to the dealer for a remap or is there aftermarket software available to purchase and do it myself? Thanks, Bill
There is a map the dealer can install for "continued use at elevation". I never did. It seemed to run just fine for me. I don't think there is anything on the market for a DIY.
