Sorry brother, didn't see this til now! I ended up with 14.7 I think? I posted in another thread but it's something like that. Not having the right gears made the truck shift constantly on the smallest crests and I ended netting better mpg with leaving the truck in 5th, as this stopped the constant shifting and kept rpm around 2k which really helped maintain speed. I was also driving 75-80mph so I bet I could do better by backing off the throttle. I've also been using tow/haul around town and it's a delight! Haha so I'll post my city mpg with tow/haul engaged soon. I suspect it will be less but the driveability is drastically improved. 456s are a must in my opinion. 410s would be better than 373, it's by no means as terrible as a Jeep since it's got so much power but it'll help the transmission shifting

I definitely feel you on the shifting. I have the 3.73s also but I only have 305/55R20s (33.5/12.4R20) and sometimes its a pain driving 75+ on the highway. thing has to shift for the smallest hills or wind changes. I will have to try to keep it in 5th next time. Does regearing change the truck having to shift all the time?

I actually sold my truck as I moved to Florida and wouldn't need it nor would it fit in these parking garages. But, yes regearing will certainly help shifting as it'll keep the rpm in the desired area.

So far I'm loving the 37s. Even with the 3.73s. I can't get the tires to break loose on dry pavement, but it still moves pretty good from a stop light. Slow, yes. BIG ASS HEAVY truck, hell YEAH !!!

I can tell my braking performance went down. Moving from 35s to 37s, the biggest difference in performance was braking. I just need to be mindful of when and how much to apply the brakes.

I did recalibrate with the AEV Procal set at 36" tires and after half a tank, the evic is telling me I'm at 12.8 - 13.2 on this tank. And that's around town and short hwy trips. I'll see where I'm at when I fill up again.

Funny, but the truck cruises much easier at 60-70 mph than it did before with the 35s. It takes a little more skinny pedal to get up to 60-70, but once there it seems to stay there with less downshifting???? I'm confused about that, but I like it!! I don't think it was the procal, because I noticed the difference before the procal.

I also have the pedal commander set at sport +2
