You got 6 inch so you got nothing to worry about there realy unless you have done a turbo upgraded you shoudn't have gone any bigger then 4 inch but to late know. Some say a stock turbo doesn't perform has well has it could if you went bigger then 4 inch. Anyway back to the point no black smoke isn;t going to hurt your engine or turbo has long has you take care of it change the oil when you should you'll will be fine, yes black smoke is a sign of wasted power unused fuel but you get it from doing up grades anything along chips, programers, fueling, injectors wil make it blow more smoke. but upgraded cold air intanks and intercoolers and turbos cut black smoke. So idk what you have done to your truck but if your just starting off and all you got done is a exchast this is what i recommend, you got a 2002 see i got a 2000 same things your injection pump is a VP44 go with the Quadzila Adrenaline, Quadzilla specails on dodge diesels and the Adrenaline come with 180 extry hourse power out of the box but it is downloadable for different and bigger tunes you can put tunes in for drag racing dyno more power for pull. For example the tuner comes with a 1000 kit already installed i have the programmer in my 2000 dodge cummins and i put the next one up 2000 kit and she will get one down the road. KNOW ONE IMPORTANT WORD OF EDVICE UPGRADED THE FUEL PUMP AT THE SAME TIME!!!! Cause any programmer is going to call for more fueling that year of cummins fuel pump sucks it can and will fail and if it happens your injection pump will fry and that alone is 1,500 dollers. I went with the Airdog fuel pump system 95 serious that fuel pump will be able to push fuel up to 600 hoursepower. Know with the Quadzilla programmer and the airdog fuel system is a great start for upgrading your cummins. THe truck will run good get down the road pretty fast and OH YEAH with those two things SHE WILL SMOKE!!! Both the fuel pump and programmer ran me about 1,200 dollars all together and it was worth ever dollar. You ever her some one talk about a smoke switch its a joke and will hurt you motor know i out smoked a guy with my setup and he had a smoke switch, then i out ran him, and just the Quadzilla programmer and airdog fuel pump is all i got down to my truck by the way. If you got anymore questiuons just ask Replies to this message: stevedebi (Mar 04, 2009 12:35 pm)

#372 of 391 i need help and im new to edmunds by jay7805 Mar 05, 2009 (3:24 pm)
Hey. Im new to this and im actually looking to buy another truck, im looking into diesel pickups, chevy or gmc 2500 actually, or a ford f-250. I know and work with ppl that own diesel pickups. I get alot of different types of advice. and alot of ppl have told me if i buy a diesel and dont use it to pull or drive far then it will just get trashed because it is not mad to tool around town. I do drive 25 mins to work one way. and pull a trailer with 4 wheelers.    I basically want a diesel becasue they hold their value, and i believe that they hold up better than a gas pickup. I also have been looking into chips for more MPG . i hope you guys can help thank you Replies to this message: oochuck (Mar 26, 2009 1:16 pm)
#373 of 391 Diesel Mileage by redbearde Mar 20, 2009 (7:34 pm)
I have a stock hight and wheels Dodge 06' Dodge Diesel 2500 4x4 QC with 103,000k, picked it up about a monthe ago. Averaging 16 mpg w/ even mix of city/highway.Was hopeing for much better! It has an AFE intake and a banks cat back. Dont think anything else, but not sure?It runs great! and Ive been easy on the throttle. The biggest thing I have noticed is the idle. As i drive the idle changes. one stop light will idle smooth as can be next stop light its like beeing in a massage chair.and everywhere in between. I have a short time left on the warranty so I am taking it back in next week to complain about idle.( they already changed lift pump,(In Tank)It was stalling at idle.Will mention mpg.But im sure they'll tell me ("yep! Thats what they get!). Any one have any suggestions on specific items I could mention to the dealer pertaining to my issues? Or any other advice like things I could check on my own? i.e. fluids,wiring?I am good w/cars(built a few 4x's)I dont have a lot of experience w/diesels.   Thanks!

#374 of 391 24+ freeway mpg possible with a dually???? by ingarage Mar 22, 2009 (12:52 pm)
I may be taking a job that requires a lot of freeway time and the company will buy my fuel but they want us to drive vehicles that get at least 24 mpg, typically cars. I want to use a dually because I need one to pull a 22,000# gooseneck 3-4 weekends a year (on my time). My business driving will be at 65-70 mph, generally level freeway near sea level in California. I would buy a used truck, looking for the right gear ratio and tranny, and would make whatever mods necessary to the plumbing and programming. Probably 2WD to save weight and height. 1st choice is Dodge mega cab short bed, then 6.0 or 7.3 Ford crew cab short bed. Has anybody achieved this average freeway economy? 5.9 Cummins likely more economical than the new engine? Is 3.54 a good ratio for this speed? Advice on engine mods by brand names? Do I have to have a stick? Do dual wheels kill me? I don't know if I'd want to tow that much with singles, even a few times a year.    Secondary issue: I realize low numeric rear ends mean tougher towing with that big load. This would be at 55 mph, so is there an automatic that will downshift to the right gear, or should I be looking at a manual? I'd go with an underdrive or overdrive if that give the most versatility. Again, I am willing to have an imperfect towing rig to get the high mpg unloaded.

Replying to: ingarage (Mar 22, 2009 12:52 pm) Your biggest problem is your trailer. No pickup is legally rated to pull a 22,000 pound trailer, and you would be in for some hefty fines at a weigh station. The trailer alone exceeds the combined weight ratings for almost every pickup out there. To pull something that heavy, you need at least a Class-6 medium truck.   As far as the truck itself as a daily driver, a Ram MegaCab is probably not your best option only because the 3.42 axle was only introduced in the last couple of years, and only available on the automatic for 2009. Otherwise, you're looking at the 3.73 with Dodge. I have a Quad Can 4x4 dually with 3.73s, and while I can break 20, I doubt that, even with a 2WD MegaCab over my 4x4 Quad Cab, you would be consistently able to crack 24. You'd be close.   If you truly need all the rear seat space, your best option is a Ford Crew Cab with the 7.3, single rear wheels, the shortbed if you can manage it, and the lowest-numeric axle. And again, you'd be close to your 24 mpg, but no guarantees of keeping it there.   kcram - Pickups/Wagons Host Replies to this message: ingarage (Mar 22, 2009 8:12 pm) kcram (Mar 24, 2009 5:10 pm) ingarage (Mar 24, 2009 9:07 pm) and 1 more...

Replying to: kcram (Mar 22, 2009 6:26 pm) Oops, I made a typo on the trailer weight. To simplify the post, let's forget the towing questions and just look at the possibility of getting a Megacab dually or any crew cab Ford dually past 24 mpg. Thanks for your recommendation kcram.

Replying to: ingarage (Mar 22, 2009 8:12 pm) Ironically, you can get a brand new MegaCab dually past 24, since the 2009s offer a very tall 3.42 axle - with the double overdrive of the 6-speed automatic, you should have no trouble reaching 24 in a 2wd truck. If your budget doesn't permit "new", you can likely achieve the same going back to a 2007.5 Ram with the 6.7L Cummins and 6-speed automatic, then have the 3.42 diff swapped in.   The tallest Ford ratio is a 3.73, so you will need to look for a very light configuration... Ford does make a shortbox dually crew cab, bit they are VERY hard to find, as not many people ordered them.   kcram - Pickups/Wagons Host Replies to this message: ingarage (Mar 24, 2009 9:07 pm) kcram (Mar 25, 2009 7:29 pm)
