Thanks JD. What tuning are you running?
Sure thing. I'm running Gearhead tuning. I've run tuning (custom and not) from just about everyone, and my hands down favorite is gearhead. His tunes have shifted the best and run much cleaner for me here than the rest.
True story - I have a buddy (200whp_liter on here) that was a chevy guy for a long time, we always gave each other crap. One night I was driving a truck to Montana for a race and we broke down about 3 hrs from home. I called Justin and told him to go grab my truck and a trailer to come pick us up. (This was back when I had a 71mm atmo and a tune, stock everything else). Long story short, 3 months later he sold his EFI duramax, and now owns a 6.4 with Gearhead tunes and an Elite 71mm atmosphere.
It's a blast on the street, and seeing as you live in the mountains, I'm confident you will love it.
