Workin on a 09 6.7 that we did 100% over exergys along with a PPE dual fueler setup. Sometimes when you put the truck into gear it will start surging and eventually stall. The truck does have some rail surge on higher throttle pulls as well. I messed around with the base duty cycle table a bit to see if it would help but it still seems to do it. I have attached the tune file and idle surge datalog. Any help would be greatly appreciated
