I just spoke to Jerry, my contact at the Cummins Hot Line. He said the TSB is 18-037-04 which was posted by someone else last week. However, this is verified and is the proper TSB. I'm getting mine done 8AM tomorrow. Good luck to everyone on their MPGs.

I'm going to Royal Gate, as that is where I purchased my truck and they have been very good to deal with. Ask for Dan.

I've heard that Don Flier in Pacific is also very good.

tsb works awesome for the starting problem not sure about the fuel mileage but its got to start before you can try this, i was wondering some mornings if it was going to start, get it done it works well.

Sorry guys I came out on this thread late. SO there is a reflash out that improves mileage? Fact or Fiction?

Cheers,

Yes, the flash improves your mileage and adjust your overhead computer!!! I had mine done last week. My overhead is dead-on accurate and I gained 1.5-2.0 mpg. On my second tank and I've done mostly town driving. However, I was on the highway for approximately 20 miles and the overhead was reading 20.4 @63 mph..I sure hope that was correct

Excellent.

As Im new to the US, whats the process? Does the dealer contact me to notify me, or do I have to ring them and request the reflash?

Cheers,

I need some advice! I'm having a conflict between "if it aint broke, don't fix it" and "more is better." My truck gets great fuel economy, about 22mpg 65-70 mph highway, but has a build date in February '04. It looks like the flash actually does improve economy but you can't go back if it doesn't.
Should I go for it or not?

I bought my truck from Lou Futz Dodge in St Louis, they were really fab. I'd give them a shot.

Tomorrow they will hopefully reflash my truck. They want it overnight to verify the "smoke on start" thing...seesh, just reprogram the thing.

If your dealer is like mine I had to call them four times and give them the service bulletin number each time [18-037-04]and still had trouble.I finally had my salesman put me in touch with owner and will be getting it done tomorrow.I'am still going to show up with copy of service bulletin.
Hoping for the best

Had I been getting your fuel mileage I wouldn't think about it. Leave well enough alone,...my $ .02.

You need to contact them. Tell them that your mileage is low and that your overhead is not accurate. Tell them that the new TSB 18-037-04 just came out and that it is for the above problems.

I think you will be happy with the flash. My overhead prior to the flash was always 2.0-2.5 on the low side, and on some trips it would be 3 or more on the low side. @65-70 mph 18+ mpg @ 63 I had the overhead reading 20.4 mpg
