So Who Can Solve This Mystery
My trucks runnin fine but it's not right and we can't figure out why.
*The EGT's are runnin higher then normal.
*The Boost is runnin higher then normal at cruising speeds.
*MPG have dropped off a little bit.
*Absolutely no smoke on take off even with Drag Comp on 5X5.
*No smoke during spool up but a slight puff at the high end.
As I said the trucks runnin fine and pulls any load I hook it up to, just workin harder to do it then it used to. I just had the RV275 injectors rebuilt attempting to fix this and that had no affect.

Nope, I've tried different settings and nothin of any significance changes.
Once in a while I get the check engine lite and two codes pop up every time. P2037 MAP Sensor Voltage and P0602 Fueling calibration. If I clear them they stay clear for weeks at a time but come back randomly.
Less then 50,000 miles ago.
I have re calibrated the APPS once already but I guess I need to check it again. Fuel filter is changed regularly and fuel pressure never leaves 16psi. Haven't smelled anything burnin like a squirrel in the pipe but who knows.

not sure if this will help.
had a guy come in once claiming the same thing, we were baffled for about a month, one day we decided for some resone to take the head off, there was alot of drag on the piston from the piston rings, there was alot of carbon and suit build up that looked like that what was causing that issue, we cleaned the holes and threw in new rings, that is what cleared his problem.
hope this helps
was just thinking as well what could also cause this
bad oil temp sensor or water sensor
