[QUOTE="golfer, post: 598500, member: 266"] it's actually the PCM basically...as rpm increases...the TUNING needs to pull BACK (lower) the inj PW...otherwise the FDCS signal will go into overlap (no 'space' between inj events)... since the PCM will not command 2 injs to fire at once (one ending its' inj as another one starts inj)...the PCM simply defaults to 0.6ms (ie, a misfire)...so that 'space' can be regained that's what causes the 'popping' sound...just PCM/chip tuning. the cool thing is...that regardless of what injection SYSTEM is on a vehicle...CR or HEUI...the maximum (available) PW is the same... it's just that the CR system can deliver MUCH more volume of fuel in "x" amount of time, when compared to a HEUI system.. the Dmax's, and CR Cummins will 'pop' as well with crappy tuning...and they don't have IDMs. ;) [/QUOTE]
