18-037-04 increased MPG

[kernen]

Finally took the plunge and had my local Dodge dealer flash the 18-037-04. When I first spoke to the service mgr. and lead tech they said they had not done the flash and could not predict results. They also said there was no going back once it was done. I really didn't understand why they could not reinstall original software. Bottomline, we did it 2 weeks ago and nearly 2000 miles I am now seeing a 2. 5 mpg decrease in consumption. Now get 17-18. 5 0n highway and 15. 5-16 in town I rarely saw the white smoke issue, but fuel use was not good imo. You still need to have light foot or it inhales fuel.

These numbers are all hand calculated with fillups to the filler neck. I sure appreciate the info. we can obtain on the TDR. thanks

Is that the same as saying that your milage went up 2. 5 MPG. Sure hope so, and if it did, I'm glad it worked out for you.

Yes, that was my inverted way of saying my fuel economy improved, I need to work on that. Was not trying to be confusing.

Mine increased. However, under hard acceration, I get some black smoke. Like I saw when I put the box on my 01. And my quarter panel behind the exhaust stays black, along with the bumper.

I noticed the soot buildup on rear quarter panel and bumper as well, I don't believe it was there before the flash. The truck runs and shifts smoothly.
