engine chugs at 50 mph--egr?

Check light on--diagnostic says EGR valve or EGR short circuit. Replaced EGR about 2,000 miles ago. Still chugs. Warranty'd so I will replace again. What next?

Mine was doing similar, only as EGT's exceeded a certain point while lugging the engine (usually in OD at 50-55 mph, I got no codes or CEL though). I was advised to try unplugging the EGR valve once it is closed (engine off), and see if that resolves the issue. In my case, it did, so I need a new EGR valve.

I should probably mention, before I had my head studs/gaskets done, the head gaskets were leaking, and the engine exhibited very similar symptoms.

No white smoke, so I dont think its a head gasket issue. Belches black smoke on acceleration and hills. EGR is not moist, but covered in soot when removed and cleaned last week. Is EGR delete needed or is it an injector issue?

You need a new EGR valve. Deleting it is a separate decision.

What head gasket brand did you use? Please don't tell me you used Black Onyx?

SCT, no studs...yet, Dual OEM intake air filter housings, Banks intercooler & intake elbow, Banks exhaust system, Windrunner ported intake manifold, Bullet Proof Diesel remote oil cooler & thermostat, AirDog2 (plus a couple spares), Power steering filter (Amsoil dual-bypass), MagTec deep ATF pan, Electric oil pre-lub pump, Dakota Digital gauges.

sounds just like mine, so I'd agree it's likely the EGR valve malfunctioning. Might be a good idea to check the wiring, just in case, especially since you had replaced the valve recently.

nope, used Ford gaskets. 60k since Christmas, no problems.

talked to Alliantpower--on the EGR--take it off, make sure that valve setting is closed and replace--but do not connect electrical and see if it runs better. If so, its likely the EGR or wiring. If not, it make be something is sticky in the turbo. Will try the EGR deal and see if it helps.
