Riding along down the interstate this morning a hellcat rolls up beside me and plays with me a little bit I heard the supercharger whine so I knew I more than likely didn’t have enough for him so from about 70 I dropped into manual mode switch to tune 5 efi by UDT dropped to 5th gear I heard him downshift as well so I knew it was on he honked 3 times and we made a pull at first I pulled on him for about half a truck length then he started reeling me in as I shifted to 6th about 3200 and pulled 6th till rail pressure fell out we were close till around 110-120 then he pulled on I was very surprised at how the lbz stayed up with him I’m only cresting that 600hp Mark Blake has the truck dialed in fuel upgrades soon to come
