At what Smarty setting are you guys seeing the best fuel milage empty?

 

Can't keep my foot out of the loud pedal long enough or bring myself to back it out of the catcher settings to find out

 

Right now I've been running #7 and empty the milage is hovering right arount the 19mpg mark, 19.2, 19.4, 18.9, ...

They are all too busy playing with it to get any real mileage gains

 

#9 cause thats the only one that i have ran

 

i was getting 15-16 on SW#7 and #9 . i ve got 14.5 to 18 on SW#1, but all this was with a stuck open t-stat. hopefully i will see better with my engine temp in operating range, if i can keep my foot out of it .

ive only tried software1 and 8 and 9,and ive found the best milage on #9.i ran all hiway with #1 and seen about 21-22mpg,but with #9 i see 23-24mpg she also seems to idle smoother and run stronger on #9.these trucks should have came with #9 loaded from the factory.

 

Been on #1 for a while now bout 14-16 Hand Calc
Scared of #9 til I get my studs in!!

 

New best ever 19 mpg on sw 7.

 

I use #1 on hwy trips, with TST box on 0. Pick up 1 mpg over any other configuration.

I had been playing with the different settings lately. Went back to #7. Last 5 tanks have been 21.something, 80 miles a day, 90 percent 60+ mph.

 

Hard for me to say.........they started ULSD about the time I got the Smarty and I have seen nothing but a decline in mileage.

I guess on the bright side, if I didn't have the Smarty.....what would it be down to?

 

I'm finding SW 7 is the best for me . Around 18 although overhead is saying 24. Could only wish. ( sure great for passengers in truck looking at overhead though, ready to trade in their cars) Found that setting 1 didn't gain me a thing. Is there anything a person can do to get the overhead a little more accurate?

 

I've seen my best on #9 at 23.

 

Don't have one myself but have never heard/read of a way... after adding fuel/hp! Sorry
