I just bought a used Dodge 2500 2004.5 4x4 w/a 6spd. I am curious about the TSB 18-037-04 flash. I have heard they mark your truck if it has been done. Where do they mark your truck? I am also curious about the increase in accuracy on the computer and the mileage increase. What has been everybody's experiences with accuracy and mileage after having the TSB done. My computer is correct on long trips, but when I do a lot of stop and go it is way off. It will say around 19.5mpg around town and when I hand calculate it, it is some where between 15 and 17.5mpg. Any information on this would be appreciated.

Mine has a sticker placed on the top of the radiator core support. Its visible as soon as you open the hood. Don't know if thats a standard location or not though. My mileage used to read way too high before the second time I've had this reflash done (a newer flash file has recently been released) and has come down some, but I need to do more testing before I claim its more accurate. Really, I don't expect it to be very accurate and just use it to monitor my leadfoot.
