MPG Post TSB

What is the average mpg everyone is getting after TRANS UPDATE.
Mine dropped to 16.9 form 18.9 before.

 

~1mpg gain

 

I saw about a 1MPG decrease.

 

went from 17.5 in the city to a solid 19.4. Ive gassed up 4 times with shell regular since the TSB. It feels more like a truck than ever now. Really happy!

 

Ok, Im super pissed.. I am getting 13mpg at best in the City running 265/70/17 Ko2's.... I know people are getting 17/19 in the city and its driving me nuts why mine is so low. Sometimes Im getting 11-12mpg on the reg.

 

I lost some mpg's right after the TSB update, but now about a month after the update its back up to where it was. From what I read in another thread, the ecu needs to relearn your driving habits and such.

 

Mine stayed right about the same, 18-23 mpg.

 

is this on your electric unit or are you just doing the math on fill up?

 

not even close. I drive like an old man. thats why im pissed. either the ECU is retarded or somethings off

 

I dont have a lift and I did remove the air dam but my MPG was this low before I did it

 

Crap gas...I gassed up at a station in N. Charleston SC not to long ago, price was cheap, it must have had more than 10% ethanol, truck ran like shit and mileage dropped to 16-17 from 19-20.

These engines don't like more than 10%

 

You're upsetting yourself over a 3 mile trip..... Show me a full tank that represents that mileage number and i'll jump on your upset train with you.

 

I'm getting similar city mileage with a manual. Same tires and air dam removed. Best I've seen on extended highway drive has been about 15.9 mpg.

 

I get about 25+ mpg on high test 100% gas...I usually baby it like an old man cause I like the mpg's...But the transmission does it's gear hunting constantly.

However I've noticed when I do give it more gas the mileage drops off to 21-22 mpg or so but it's runs/shifts better...

It's a trade off...lower gas mileage equals better running/shifting and good gas mileage equals poor transmission performance.

 

I lost 1 to 2 mpgs.

 

Its been this way since i bought it. I run somewhere around 11-13 on average city.. or so it says

 

is this what the ecu says or what youre acutally getting? I am gonna run a tank and divide the miles I got by the amount I fuel up with. should give me a real number as to what Im really getting.. I think the "mileage" from the truck is not accurate.

 

1.5 mpg gain

 

Mine stayed about the same 17 city and 20.5 on the hwy

 

I've stopped using the ECU and my mpg went up immediately!
