That all sounds logical Beau but i have to assume what we actually do when we "turn up the fuel" is increase pump pressure which would explain varying results from individual trucks as only good clean injectors will allow more fuel to be
forced through due to the increase . Maybe we only get away with this because its indirect injection ?
I don't care what anyone says these are tough engines so one cylinder being stronger or weaker than the rest would be water off a ducks back in the short or medium term .
What if the squirt hole was made slightly larger and given an alternative pattern allowing the increased flow to "mist" mixing fuel and air for a more potent cleaner burn , timing and pressure need not be altered the only thing we need is more air which we both have already .
I'm not entirely convinced ,web searches tell me very little indeed accept it seems to be the first mod the Cummin's guys do .
I questioned the warranty given the distance offered by the seller and the answer was a very off hand "send them back if you want but nobody ever has" which would be reassuring had it not come from the seller
CAT is out there i think so it would be nice to hear from him if he knows someone running these injectors .
I don't know but the "slightly quieter engine" says to me balanced .
