What year is it? Do you own a diesel truck? What are you comparing it to? If you are HOT RODDING your BOSS'S truck, shame on you! Diesel's will have some turbo lag at take off unlike any gas engine.

im about 90% sure its 2006 i drive a 98 12 valve although i have got some work done to it there's no reason why this thing should feel weaker than my 98 all i have is intake exhaust and very little pump work. i bought the truck used with those mods already done i just was worried about this duramax i would hate to take my bosses new truck back to him broken you know. i have done some calling around thats how i found out about this place and i have been told that chevy diesels are a great diesel for speed but are weak when it come to pulling something i dont know thats why im asking

WEAK when PULLING? I DON'T think so. What MORON told you that?

Yea so weak in pulling they beat all the competition:D . Stick to the Dodge forums.

chuck hassel, diesel tech from english chevorlet crystler dodge. the load that im pulling is maybe 2,000 pounds tops my cummins dont even notice it but this truck you can almost watch the fuel gauge move and it seems to have a really hard time with it. i was noticing a grinding feeling up to about 30 mph but other than that i really didnt notice anything else out of the normal

maybe if all that was in the competition was a bmw and a voltswagon. i would talk to the dodge forumns what ever they are if it was a dodge problem but my dodge dont have any problem pulling this light load im asking because i think theres something wrong but i'm not sure. im not trying to pick a fight but this lack of power concerns me. (its not my truck)

Actually, in all the reviews I've read the GM diesels are rated #1 for acceleration whether loaded or unloaded, towing or not.

It's possible that your truck has an aftermarket tune installed and you don't know it.

my truck dont have any programmers in it its a 12 valve they dont make any to my knowledge

and other than an intake from amsiol me bosses truck is completaly stock with 18,709 miles on it

what about the grinding from 0-30 is that normal

I know just from expirience over the past week. One bad tank of fuel and a Fuel Filter with 3500 miles on it is shot and the truck runs like garbage. No power doesn't shift right. Maybe hes due for some maintenance .

If you're truely looking for an answer change the fuel filter and check the air filter, when they start to clog you can get reduced power.

I think you need to take the truck back to your BOSS and use your SUPER FAST, NO PROBLEM PULLING 2000LB LOAD 98 DODGE truck for work and stay on your Dodge forum. We don't welcome Brand bashers on this site. Good luck.

At this point I'd have to suspect driver abuse. I've never heard of anyone having grinding noises or lack of power with a 2006 GM truck (or any other recent model for that matter).

I think I have solved the problem. When you got to work this morning and took off in your boss' truck, you didn't notice that someone had chained your Dodge to the trailer you're pulling. That grinding noise is your rims dragging along the asphalt behind you and the apparent lack of power is simply 7000 lbs of dead weight being drug along for the ride. :D :p: :eek:

Either that, or the e-brake:eek:

lol guys im not trying to start a fight im just telling the truth. the only answers i will get from the dodge place is tell my boss to trade in his chevy for a cummins,but i have not thought about the fuel filter he did fill it up after we mowed are last yard yesterday so i would have plenty but its about 4 miles from the station to his house and every thimg was fine i didnt notice anything coming into town this morning but when i got to town and started all the stop and go stuff i could really notice the lack of power. i going to check the air filter right now i will keep yall informed on what we find out

the filter was a little dirty on the bottom but not enough to make a difference

the air filter that is

Hey, yeah, double check the parking brake. I've been known to drive around with that on a time or two. :duh:

well good news chuck came by on his lunch break and we changed out the fuel filter. there was trash floating in the canister the filter looked like it had been mudsling and the truck is a completely different truck now. never knew filters played such a big role thanks for all the help although some of you guys wanted to talk more crap than help

So how does it compare now to your 12 valve?

Yup, fuel filter it is. Usually something extremely simple. And don't mind the Dmax guys, they're just proud of owning the best. ;)

You seem to be a stand up person, not only did you fix your bosse's truck but you did not let these people get to you, you said nothing wrong, obviously there was something wrong with the truck, I feel embarrassed :( but I am proud of you!!!!!!!!!!!!!!!!

Hopefully he is better at changing filters than he is at piecing a sentence together.

come on guys leave him alone....he's probably amazed on how well the truck is running now....and let him get back on mowing!!!! teenager i'm guessing?

Well I'm feelin sorry 4 him because he has to wear his lawnmower ear muffs home driving that 12 valve. :D

This comming from a Harley rider????;)

those mechanical 12v motors are damn good! no electronics needed to run it- only one wire. plus, they sound like a diesel- not like the new diesels that sound close to a gasoline engine!

when I first read this i thought, air and fuel filter or maybe an injector stuck. Not too many injector problems on the lbz's. I cant knock the guy for his sentences, cause I dont type too well either. If it were an injector problem shoudl notice either overful oil (fuel getting into the oil) and a rough running truck. The druamax shoudl def be quicker. But them old 12 valve really really really pull, they arent quick but they love to lug down and pull. The are reliable and easy to modd, jsut a fuel screw away cheap power. If i could build a truck tid be a 12 valve, allison auto sfa, and chevy body.

We still haven't heard how the d-max compares to the 98 dodge now. What happened?:D

that must be why I sold my 97 and 99 dodge diesels and got duramax trucks.

My dodges had a hard time towing my loaded race car hauler up hills.
My duramax's and even my ferd have no such problem.

You guys want to see 12-Valve potential check out Chris Werner's 01 Ram on pgs 78-84 in the September 2007 Diesel Power magazine. That beast has wrapped dyno's and shown #'s of 1237 hp and +2400lb-ft!!!!!!!

I'm a Duramax fan all the way, but that shit is CRAZY! :eek:

I too am a cummins fan and that truck is damn impressive but I have to say that most of the trucks in that power range are modified class sled pullers that recieve sustantial engine maintenenance on a regular basis. I am highly skeptical about the longevity of a truck making that kind of power used in his application (recreation and daily driver). I think he's going to scatter that thing all over the highway one day.:D

Hey feel sorry 4, dont worry about being mistreated here, some of us are trying to make up for the 6.2 and 6.5 years, best wishes for your cummins, they are good engines. D.

I tell you what when you start comparing 98's to 98's, the 12 valve (since we are talking motors) is 5000 x what the 6.5 is. NO one can knock that, can the 6.5 be made reliable and power, but the 5.9 is reliable and as powerful as the 6.5 out of the box

How about those 350 converted diesels of the late 70's early 80's, those were classics for gm diesel unreliability. D.

Did we take the parking brake off ?

He was just not used to the fact that he could actually hear other things besides the 12V rattling away.
