New member - seriously considering a HD Hemi

[GOATram]

Terrific answers so far. Not sure I mentioned it, but there is a Laramie mega cab with one of the dealers around here with a 3.73 that I am thinking of looking at tomorrow.

Does the pedal commander make a noticeable difference in the throttle response? Does it void warranty?

I won't duplicate the answers provided here with respects to my experience with the 2014 CC 6.4L Big Horn I owned. I pretty much would echo what most are saying here.

I towed about 9K out here in the West including a 6% grade (up and down) I had to traverse routinely and the truck did fine after I added a cold air intake, freer flowing exhaust & a programmer with a custom tune (Diablosport I2 + Hemifever tune). There were times I wished I had more gear vs. the stock 3.73's I had and it was on my to do list. Mine seemed to struggle more as the ambient temperature rose.

Mileage was pretty much what's been noted here. Best highway mileage I saw was one section of a trip over fairly flat ground (MN to SD) at 18.5 mpg. MPG did improve after the CAI/exhaust/tune install for hwy mileage.

I've linked a video of a WOT pass with the intake/exhaust/tune installed below.

No idea on resale. My truck died due to a collision with an unattentive driver after just less than 2 years of ownership.

If you are going to keep it for 10 years, I'd say no one I know would be able to come up with a reasonable number due to numerous variables. If you want you can find a depreciation schedule online and do some calculations but that's only gonna put you in the ball park. It is true, however, that a diesel truck will have a higher resale.

I only had 22K miles on my truck when it died and I was very happy with the truck.

The Pedal Commander will not void your warranty. It provides much better throttle response with many settings to choose from.

39000 + on my '16. Trouble free except for FCA recalls. I pull a 34 foot TT, 3.73 gears. No complaints.

One of my major reasons for buying a 6.4 Hemi instead of the Cummins was money. $9200 in my area for the diesel option. Well, I can buy a lot of gas. At my average of 2.99 for mid grade I can buy 3076.93 gallons of gas. At my MPG avg that’s 43,692.3 miles. Will that change, probably but still a major decision for me. That’s not even factoring in Cummins Maintenance. I say that because my brother-in-law formed out $7000+ in maintenance items during the first 3 years of owning his Cummins, he’s back in a gasser now.

As AF stated, my decision to build and order a 2500 with the 6.4 was the option cost of the diesel, the cost of diesel fuel in Ca and the additional maintenance that comes with a diesel. When I looked at what we would be towing "wet" the 6.4 with goose neck option was the right match.

Because it is not believable and was a justification post. OP had very specific questions and not one of them was why you chose X engine over Y engine.

Check around on Youtube for some Pedal Commander videos on Hemis. Most people are pretty surprised by the difference. I instantly noticed the difference. I always say it really just made the truck just feel like it should from the factory. You can apply only light throttle with it to get the engine to start working which I found very beneficial in such a heavy vehicle.


First time I started to swear by this thing was when I noticed myself cruising up to a long moderate hill in the back roads and was only getting on the gas a slight amount and the truck would either hold its speed or gain speed and would never down shift. When stock it would always end up down shifting on the same hill. The engine and tune is exactly the same as stock but just by tweaking the throttle response the computers are doing things smarter. Again, this is nice in a big heavy truck with the old 66RFE..

On the same hill my Charger (no PC) will hold whatever gear its in but it is so much lighter and has a ZF 8 speed.

No it will not void warranty nor does it add HP. It just takes the lag out of the drive by wire.
Yes you’ll know it’s response as soon as you hit the go pedal. It has 16 different settings so you can adjust it to your comfort zone.
Absolutely the best mod you’ll ever have in your truck.
I love mine. And wouldn’t trade it for anything. Well except for maybe a female nimfo. Then I’d just order another one

I traded my 14 2500 6.4 that I bought new for 39k and they gave me 33k, I had 50k trouble free miles. I do miss the truck, gearing sucked, other than that it wasn’t great. At 10k plus towing quite often I would opt for a cumin’s.. 10k is about as much as I would want to do with a gas motor. Remember you get the exhaust brake with the cumin’s which is great for towing. Either way both are great plat forms.

Yep, I actually answered his questions in full, but hey to each his own.

Guess it’s all in what you’re used to I came from an 08 f2****ty with the 5.4 to me the 5.7 in my 2500 is an animal

Beautiful truck. I hate when stuff like that happens.

I just want to add that I'm lucky to get 13 mixed mpg on my truck. Seems like 10-11 city for me. But my truck is never empty being a work truck. 15.3 highway going to the beach a month ago.

 

[Firebird]

I have always towed with a Cummins, they just make the job very easy, and fairly good economy to boot. I've not towed with my 6.4, but from all I have read, it is quite capable, but I'm in Florida, no hills. If I lived in the mountains, I would want the Cummins again.

New guy here with similar concerns/questions as the OP.

My truck will not be a daily driver and would only be seeing 5-6000 miles a year, towing about 6000 lbs of enclosed trailer with motorcycles.

I'll be replacing a Ford excursion with the V10.

Great info folks.

The 6.4 will serve you more than well enough.

Here's a question concerning gear ratios...Most dealers don't list the gearing of a vehicle, and few seem to know how to find out. Is there a 'axle code' on the door jamb and/or tag on the rear diff that shows the gear ratio? I would definitely like to have factory 4.10's.

I could not find the elusive 4.30's in the excursions when i was shopping for that truck.

 

[G. Mcpherson]

It will be listed on the Window sticker.
