Hey there. Can you guys help me out with a problem I have deciding on if i want to keep my SC. Keep in mind I live in upper Minnesota so we get climate changes from 95* above to -40* so it is a pain in the ass to tune all the time. For all you guys without a SC how does the truck get along with loads? Going down the interstate, climbing, mountains and hauling. I only had the truck for a couple of months before I was talked into putting the SC on. I am just tring to weight out either way. I STILL havent gotten the hang of tuning it yet and I really do not care to pay for the extra for premium gas either. Thanks for your input!
