:dunno:We are coming back from vacation and pulling our camper when the turbo really starts to whine alot and the exhaust temp is now way up and blue smoke is coming out of the exhaust. also the exhaust has a bunch of black soot on it at the exit of the pipe. Is it the turbo or what. Truck still making power but getting more and more smoke. Even at idle it smokes light blue. Thanks Wayne:dunno:

Welcome to ORG! ! ! not sure of the cause of your problem but possibly a leaking injector o-ring possibly but as far as high EGT's do you have straight through exhaust or still have CAT AND MUFF??

You said Exh Bac Probs does the exhaust sound funny if so could be a Stuck EBPV(Exhaust Back Pressure Valve) and another problem IMO I wouldn't stack a Superchips and Banks together get those out of there CLEAR the Codes and see how it runs then.

Would a exhaust back pressure valve cause the it to get a high pitch wine out of motor while making it work. Also the light blue smoke could be a bad injector and they just went bad at the same time. Would the stuck injector or the EBPV cause the high temps. The tuners have been working great together for 85000 miles. Thanks Wayne

yes the ebpv will make a high pitch and i bet on the bad oring on the injector for the smoking issue.the ebp sensor will not make it smoke or wine.no matter what is on it.

Okay another Idea???

It is really getting more smoke out there. Could this be my turbo Giving up the ghost. Really smokes alot when you let off and boost drops. And I mean really smokes. Thanks Wayne:dunno::dunno::dunno:
