6.6 GAS with 37 inch tires

[Tyler Marchak]

Hey y’all! Looking to see if anyone has 37s on their GAS 6.6 HD truck. Power, mpg, drive ability, that kinda stuff. 
 

Please don’t provide your opinion if you don’t have 37s and 6.6 GAS truck.

I have a 1988 ford ranger with 29’s with a lil diesel swapped in. Goes decent even in 4wd. Does that help?

i have 35/12.5-20s and have plenty of power, pull mid size tractors and other ****** just fine. youll prolly loose a tad more but itll still do truck stuff. if you feel it has drained too much for you to bear then you have two great options, the new procharger kit or the new whipple blower kit both are tuning included(personally id go with the whipple for more TQ over the centri)

I put 37's on around 3K miles ago. Added the Pulsar LT at the same time to correct the speedometer, and throttle sensitivity. In my opinion it drives the same if not better than stock because of that. MPG is around 12 since then..i'll attach my fill-up records.

You bet! I won’t even read the rest of the replies. Will it go over 25 mph?

 Awesome! Exactly what I was looking to understand. Seems good to me! Over 10 mpg in our new fuel efficient world? Is good? Hahaha!
