Have you done the update and, if so, are you satisfied? Heard both opinions. Some say if your truck runs well without not to get the update as the update has caused some mileage and drivability issues. Some say that the update worked well.

If this is the update concerning the problematic exhaust temp high sensors, then I would recommend you get it. The problem is that if one of the sensors fails and registers extreme high temp, it will give you a "stop safely now" message and quickly shut down the engine with little advance warning. Then it cannot be restarted for at least 30 minutes, with no guarantee you can drive it very far without it happening again. That happened to me (2012 F350 6.7). Had to have it towed to dealer for warranty sensor replacement. Fortunately it did not happen in the middle of a highway or intersection.I have experienced no noticable difference in performance since the update about 6 weeks or so ago. And that includes towing the 5er.

I just got it a few days ago. Didn't notice any problem before or after.

Had my 2011 done and the mileage seems to have dropped off.

I had no choice, if you read the letter it states as being mandatory in Cali and MA....so being a ma resident im left with no choice.The update I got was in reference to emissions

2011 - 2014 6.7 Powerstroke PCM update. Did You?

Mines been normal for the last 3 weeks since update. Skyhammer, I live in Windsor north of Santa Rosa. Diesels get a OBD2 interrogation and mod inspection plus a snap throttle smoke test. 8 miles north they don't even test cars.

Mine was done on Tuesday and seems fine. My dealer gave me a slip for the DMV renewal as well. I've had my 2011 4 years now and have not had to take it for a Smog check yet, my 2001 went every 2 years like a car.

I don't know where you live, but in my part of N.Calif. We don't have smog checks.

My 2013 was done last Feb. No problems at all. No impact on mpg or DEF mileage that I can see. I do concur with Lumpty about the trans shifting smoother. The other thing I noticed is that it seems to run a little better when cold, especially when in first gear.

Had it done a few months ago. It changed lots of things under PCM/ECU control. I'd just say it drives "different". Mileage is pretty much the same. The two really noticeable drivability items from the reflash are that at highway speeds, it is much quicker to downshift out of 6th instead of building boost and torque to increase speed if throttle is slowly applied; the other is that the transmission has much softer shifts. Not old E4OD mushy, but enough that even my wife noticed the difference when she drove it.

I also had the DEF massage "800 miles to empty" and mine also only took 2 gal. Other than that no issues at all to include mileage.

under certain conditions...it might act up...or go into limp mode...or
stop the vehicle or kill a component on the spot...

I'm curious, since you don't own one of these trucks, why this is a big concern for you?

had mine done a few months ago---only thing I noticed was the DEF was saying 800 miles to empty immed after the update---only took 2 galls to fill it up, no issues with it since then
