Talking 6.7 Cruise Control Surge

I havent had any major problems with anything on my truck and ive got 17000 and I absolutly love it. Although there are 2 Minor problems. 1st the cruise control surges only on level terrain, once I hit a decline or incline surge is gone?? Took it to the dealership and got the famous "we cannot duplicate the problem". 2nd that damn DEF burning off somehow someway makes it back into the cab and its almost sickening to smell it everytime it re-gens. Any one have any suggestions for theese 2 items?

Is your turbo surging with the cruise set? Mine does it something awful...pretty dang annoying. I live in West Texas so the wind BLOWS ALL THE TIME and thats when mine seems to do it the most!

The motor surges, I can feel it in my seat, but the speedometer doesnt surge. I never thought to look at the turbo though.

The truck is also a smart truck if you will, the crusie control will actually control your speed when there is resistance, incline, descending etc. Its new to me, never had a vehicle take control like that.

Next time it does it look at the boost gauge, it will be going nuts. The tac will be holding steady. I can hear my turbo spool up when it starts to surge...I posted the same thing a couple of days ago asking if anybody else was having the same issue. Apparently it's not uncommon.

Just noticed my turbo spooling tonight with cruise on. Same surge feeling I think as others are describing. Speedo and tach steady, turbo up down up down. Cruise set at 70 no hills or wind, thought it was weird.

My truck did the surge thing on my way home from North Dakota a few weeks ago. Cruise set at 70 and it went into regen. I actually have the occurrence on video. I got home and inquired at the dealer and the service advisor looked at me like I was crazy.

I'm really getting fed up with "if a check engine light isn't on or you're not on the side of the road, there isn't anything wrong with your truck" .....it's a crappy way to handle things.....

This is from Ford. " There have been reports of a reported surge with boost gauge flucuation olny when is cruise control on some 6.7 vehicles. The customer may see the boost gauge flucuating and hear an audible change in the engine.

Engineering has found that this condition typically occurs around 1,500 RPM and at speeds between 60-65 Mph only while cruise control is on. This characteristic will not be present while using the A/P pedal. This is a nornam characteristic and is caused by the PCM trying to keep the torque set point and speed the same.

Due to the stack up tolerances between several components (turbochargers etc.), some vehicles are quicker to respond and some are slower to respond. Engineering is aware and has stated that it is a normal charactistic of the vehicle. No further diagnostics or repair is recommended at this time for this symptom."
