I have a 2001 3500 dually 4x4 quad cab long bed, stock tire size, nv4500 5 speed with 3:55 gears. What is the average fuel milage expected from these trucks? The only "mods" done that I know of are a FASS ddrp pump in factory location and the exhaust has been replaced but nothing crazy. I measured the tailpipe it's 4" but have not measured the rest under the truck yet. So to my knowledge it's pretty bone stock with 141k on the clock.

 Last I checked I was at about 15mpg. Mainly to and from work, about a 20 Mile drive, about 5 of that is considered city the rest is state route 60mph or highway about 65mph.

 Just curious if I'm around the norm for what I have. Thanks.

@Mopar1973Man Thanks your help is appreciated.

 

I don't have $1000+ to drop on the Quadzilla Adrenaline and the 7X0.010's.   I'll move forward with this once I have the play money to throw at this truck.

 

Yea I know my injectors have high mileage , wish I could do this now. Good to at least know that the quad adren & 7x0.010's are the next step.  At least I know my mechanical fuel boss pump and stage 2 clutch will be able to handle these mods when I'm ready to roll.

 

I would jump at the Quadzilla first. You'll be able to tune around wore injectors to a small degree. If the pop pressure is low you can retard timing to bring the injection event back to time. You can watch the engine load at idle to determine when the injectors should be changed. I'm idling at 7% now from the orignal 13% I had went I first installed. I've got half life for my injectors.  Then you are aware of the injector health and when they need to be changed then you can set timing to make up for the early events because of low pop pressure.

@Mopar1973Man, would those tunes yield the same results on my truck? I don't have a tuner but am asking out of curiosity. Being I have a dually I don't think I will ever get the high mpg's that some do anyway. 

There are variables like injectors and pumps that are going to be a bit different. Like my injectors are 7 x 0.010 but popped at 320 bar. This changes timing and makes the injector fire late so I can add more timing that most with standard pop pressure. Now at this point I'm wore down enough to be a standard 7 x 0.010 at about 300 to 310 bar now. My next release of tune should fit more people. Injection pumps wear as well and the cam ring will loose some of the lift on the lobes and the pump get a bit shorthanded. Again a variable... So for the most part it should work but might require a bit of tweaking. Degree here or there of timing or fuel map.

Good to know, thanks for the info.

 Thanks, I was just curious. I haven't ruled out a tuner forever. It's just not in the budget anytime soon for sure. I'd like to get gauges, new injectors, big line kit ( tank to VP) just not sure where to start to be honest. It's a good chunk of change just for those mods. 

Quadzilla

Fuel line

Gauges

Injectors

 

Quadzilla could provide gauges hence it could take lead. Fuel supply is important so fuel line next. Gauges and injectors could be swapped but then you can upgrade either one or both.

That's why I don't think I can afford to ever sell my pile, too invested in it, need to put few hundred thousand miles without brake down, then I'll probably just give it to my kid and say here you go good luck....

Told my son he was taking me on my last ride in mine. he told me it better be running good or he was calling ahead and have them dig a bigger hole. Folks in my family dont get attached to vehicles like I have.

I feel at times we fail at certain things as parents, but then again all new generations to come think that previous ones were dinasors. Three is a line in send that needs to be drawn though to all this nonsense.

Maybe not. My old man grew up with clutch. He was glad to get out of it. Of his 5 kids I was the only one to embrace it when l grew up. But l am afraid it is the dinasaur now.

If my youngest ends up with mine I’m going to have to make sure I stay alive long enough to make sure it don’t end up with 44” tires and an 8” axle dump, I don’t know where he learns such language,  

 

maybe I should just do@dripley route and just go with a big hole, at least I will be able to Rest In Peace 

 My kids are already asking who I am leaving what to when I'm gone. The biggest items of interest are my farm, my trucks, my Harley and my guns. 

 I keep telling them I'm leaving it all to my 5 year old grandson. Lmao

 I'm hoping I have many years left to enjoy the stuff myself. I'm not even 50 yet.
