TSB 18-009-06 and Mileage Improvement

I had the first half of the TSB done (dealer could not do the second half and I am still waiting on them). The biggest difference is a jump in mileage. My last tank gave me 27.0 mpg. That is 1 mpg better than any previous tank.

My trip computer said I got 28.8 mpg but I used 15.004 gallons to go 406 miles. 406/15.004 = 27 mpg.

Has anyone else noticed a jump in mileage after having the TSB done?

I've had it done, but did not notice a change. I've changed too many things on my KJ to notice changes. Larger tires, lift kit, extra weight by adding skids and front hitch, ect. ect. ect...

Also, we are getting out of winterized diesel now so than may improve mileage as well...
