6.2 What's it good for? Just about everything.

My throttle springs are not that stiff? Or maybe I just have gotten used to it. But I jump back and forth from a 2012 Cummins , 98 Cummins , the burb , the crew cab , and the my 93 6.5 plow truck . All of the. Feel about the same to me
 
My floor is dented just in front of the pedal so it's not natural for the foot position.. maybe I should just hammer it out.
 
Depending on the day.. it can range from 50s up here and 90s down where I work,

We came so close to 50 today. Course it's cloudy so it was 48 today. And it is still 46. I doubt we will get much lower than 40 tonight as long as the clouds stay
 
I must be a gorilla cause it's only tough to get it to kick the lockup out when I'm cruising.

Getting about 19.5 mpg it seems no matter what
 
The MPG's are what I love the most about these little motors .

It's allowed me to actually drive a square body GM again as a practical vehicle and not just a toy
 
I dd the cucv with the rubber overdrive. I am a bit irritated it won't start without glow plug use in mild weather. 55 degrees this morning and I'll have to cycle em. Sensitive.

This is my alibi. If I were getting 15MPG (or less!) I would never get around to actually driving the beast.
 
I usually am DD'ing my 6.5, but it is loaded with the camper at the moment. Not that I can't drive it with it in there, I just choose not to. But I'm only squeezing 15-17mpgs from it, which is still better than my Jeep.

I do have a very heavy foot though...:burnout:
 
I watch my tach very closely on the highway.

Cruising 1800 and below yields 15 - 17 mpg depending on altitude and terrain, but if I want to go 65 and up, I'm running 2150+ and mpg drops to 14 - 16. I may experiment with different precups - I have the big turbo diamond cups, and am curious what the economy ones would do. The engine is also very sensitive to fuel timing and metering changes; small adjustments seem to yield outsized results.

Looking way down the line, there's enough gear and tire to run a GearVendors and have double OD, but it sure is expensive. Maybe a good deal will come along. Interestingly, just pumping up the 38s to 45psi also added about 1 mpg on the second extremely flat leg of our drive to Santa Fe.

Do you guys that are turbo find it hard to maintain the speed limit in overdrive?

That's a really vague question. Driving down a 25MPH residential street I doubt any of us have problems. :dunno:

I do a lot of my driving at 55MPH and <2000' elevation, that's the most common speed limit around here. Eric cruises at 80 up in the mountains. Aerodynamics and altitude take over, both power-wise and mileage-wise.

No. After the turbo, and with a carefully tuned 4th-unlock, I have no problem maintaining 65/70 in OD, which is my personal speed limit.

No sir.

70 mph is right at 2,000 rpms.

I'm not impressed for an unloaded, turbocharged 2WD rig with new injectors cruising @2000RPM. Your rig isn't *that* much heavier than the short-cab GMT400 rigs that I have driven. And your aerodynamics should be quite a bit better than my square brick.

But YMMV, there is no doubt. Maybe your foot is the problem. A Cherokee should be 17-20MPG according to the EPA.
