Message: [QUOTE="Charles, post: 1295332, member: 103"] Dial pulsewidth back and have the truck dialed for the current setup [i]now[/i] without buying a single thing you don't already have... That was my whole point anyway. Money isn't required to fix your problem. Turn the program back to stock and there's a chance your egt problem would vaporize in thin air. Truck would probably drive like junk and be super over touchy because the low power and off-idle fueling would be too harsh, but if the stock file has less pw you could instantly see the change to egt. And it would NOT make stock power! More specifically, you need the ratio of rail pressure to pw to increase. For a given rail you need less pw. Right now you are "under the curve" where the program is calling for too much pw for a given rail. No matter what you do with the pedal the ratio is always wrong. Ask for more rail with your foot and you also get too much pw right along with it. Truck's always hot and doggy. Drop the pw and the truck will crispen up, egt will drop and the rail will naturally rise on the top end too. All of a sudden your pump will be fine. In other words, unless the power output is lower than you want, just fix the state of tune. I think the main issue is that tuning the 6.4 is uncommon and you guys just run a bunch of canned crap and swap parts around until it runs decent. I can't think of any other reason not to simply cut some pw and give the poor truck a break. So many posts for such a straight-forward issue. Surely somebody knows how to shallow up a fuel injection pulsewidth map! [/QUOTE]
