Have you taken your truck back to the dealership for the lastest reflash? You might want to try that before spending money on a module that might void your warranty. Reflashes are free if you tell them you have long cranking times before starting and then you get white smoke for a few minutes. Give it a try, nothing to loose.

How many miles on your truck? My mileage was 15 empty 7to9 towing till around 20000miles continued getting better till around 80000miles at that point I was getting 19to21 empty 10to14 loaded my truck seems to be effected a lot by winter blend fuel like loseing 1to2MPG just installed a smarty ran a 12000mile trip played with level1 and 3 found it to give 1to2mpg along with extra power level gave the best mileage with my combo Randy

My 06 started better new than it does now. I've been through about 4 flashes to fix other codes, ck eng light annoyed me, especially on a new truck. Don't have any light for about 2000 miles now, but ever since the first flash my cranking time doubled or even tripled. To flash or not to flash, that is the question..... On my overhead, the best mileage I have had was when it was on it's first trip home (400 miles). But then again, my overhead has lied 2-3 mpg (overstated) than on paper. It showed 19 at the end of the trip. I average 13-14. 5 around town if I take it easy, 16-17 hwy unloaded, 8k miles on truck. Not disappointed it will get better with more mileage.
