Towing With Latest Flash
I got my truck flashed a week ago, and this past Friday took my fifth-wheel out to Harrisonburg for the weekend. The trip out was 258 miles and I had two complete regen cycles that lasted 13 and 18 miles each. The truck didnt perform any different then before the flash, so no worries for me there. Filled up once with 17.335G, and again the following day I topped off with 22.026G.
Now I didnt go all that way just to haul my fifth-wheel, so the wife and I stopped at a few of the wineries in the Shenandoah area between her antique shopping. Fun for both of us. My leasure driving was 202 miles and had one complete regen lasting 11 miles. Before heading back to the campground I topped off with 8.589G.
On the return trip today it was 257 miles with one complete regen for 13 miles. I made it home on one tank and pumped in 29.880G.
On the way out I went by the scale and was at a GCWR 24,640 lbs. The trip home I weighed less in the wallet and truck, so that might be the reason for only one regen?
I paid $3.85-3.99 a gal for fuel. Hope the price holds or drops before our trip to Tennessee this summer.

Sitting in Pigeon Forge right now. Diesel is $4.20 a gallon on Black Mountain but is $3.95 all the way down I85 and I40 and in town in TN. Still cost more for 5 to spend all day in Dollywood than the fuel to get here

---you stated - On the return trip today it was 257 miles with one complete regen for 13 miles. I made it home on one tank and pumped in 29.880G. ----
So if this is a math story problem - which I learned to hate back in grade school - before calculators - looks like you towed that big ole trailer and got about 8.601071 mpg
Not that bad !!!!

Thanks for the report, I will be updating soon as it is almost time for service.
My boat only weighs about 7000lbs loaded so its nice to hear that big haul you have is no problem. Did you go through the trans re-learn process in tow haul and or normal driving first?

I drove normally like my service writer said to. I told him I would haul my fifth-wheel in about a week and he said that was more than enough time for the trans re-learn the shift points.

That flash was not supposed to do anything to the performance..just improve reporting.
We have the exact same truck "JOB 1 '08 F-350 4X4 LARIAT CC 6.4 DRW 4.10" and it is rated at 23,500 GCWR so at 24,640 lbs you are running way over so @ 8MPg is not all that bad. We are at 22,600 lbs towing a 06 Montana 3400 and do 10/11 on average.

I just drove from South Padre in Texas to the Phoenix area. For starters the lowest fuel price we saw was on the island @ $3.89 the highest was in Benson AZ. $4.39 On our first tank of fuel I saw 3 regens and got my best mpg. so for a while I thought the new flash was responsible. Now I realize nothing has changed other than my cleaning exhaust message no longer stay's on and I can't tell when it's done. My 450 has the 4.88 rear end and we saw a little over 10 mpg for a high and a little under 7mpg for a low. The wrong way to look at this is it now cost about 50 cents a mile to pull my 5th wheel down the road.

Towed 348 Miles today. Florida I-4 then I-95 to the 33 miles marker in S.C..not a single
regen. We are heavy after 6 months in Florida and ran 70 MPH most of the way..faster than we usually do. Averaged 9.5 which surprised me... Fuel at Flying J 4.17 to 4.07

The mileage backstop for regens is something like 675 miles, so if you have a cracked DPF that isn't triggering regens on backpressure, the regens will occur at that mileage backstop interval.
