Getting the reflash for my truck tommorrow. Dealer said it should improve the mileage along with the regular break-in of the engine.

 

do you know what the TSB # is for this? also, isn't it only for trucks built before a certain date and what is that date?

 

The build date on my truck is 10/2005. Anything after Jan. 2006 should have it done. The TSB is 18-05-06. It is not an mpg flash, but rather a driveability one. At least thats what my guy at the dealer said. It has, according to him improved people's mileage up to 2-3 mpgs. We'll see. I'll report back this weekend!
