I was at my dealer a few days ago and saw three 08 cab and chassis 350's. I was checking them out and noticed they had no DPF OR CAT'S, so i asked my tech adviser what was up with that. He said the trucks can be ordered without the emission equpiment like the DPF and CAT if there used offroad in applications like the railroad or mining operations offroad. The trucks are not carb certified so you could never register them but this leads me to believe that there is a factory tune out there that would delete the regen. If you were to run this factory tune would they still void your warranty. Just thought it was intresting and wanted to know what yall think.

 

I think that as long as the DPF is there that it has to regen or it will plug completely and start to hurt performance and economy.

 

I agree, but if you remove the dpf and the cat you would'nt have that problem.

Not saying this would happen, but if you told the dealer you wanted to use the truck offroad, would they allow you to remove the dpf and cat and reprogram the pcm to kill the regen. Of course you would have to pay for the reprogram but i wonder if its possible. This might be an avenue to change your truck and kill the regen without the loss of your powertrain warranty. Just a thought.

 

The intresting part of this is that the exhaust system on the trucks i saw looked factory, so there has to be factory parts that replace the DPF and CAT. The tune is factory, so you havent installed any aftermarket parts if you use the factory DPF and Cat delete pipes and the factory tune.

I dont know how factual the information i got from you tech is but if it is true the only problem here is getting a dealship to bless the changes for (OFFROAD USE), mabey this is not possible but the idea is intresting none the less.

 

Just a question, but how would you be able to register the SuperDuty? How you going to blow smoke up the MVD?...even if the dealer was dumb enough to believe you?

Dreams...dreams...dreams...

Your mention of "mining operations offroad." reminded me that it is possible to buy Dodge 5.9 Cummins diesel trucks for "underground mining operations", their "factory tune"; 175 horsepower, 317 lb.ft. torque @ 1,000 rpm, 25 mph maximum vehicle speed(option to increase that to 40 mph)

 

Any chance of getting some part numbers off the pipes on those trucks??. It can be done, it's referred to in the '08 owner's manual.

 

Hey! If a seventeen year old kid can unlock an iPhone, somebody can figure out how to do this!

 

[QUOTE=biz4two]Just a question, but how would you be able to register the SuperDuty? How you going to blow smoke up the MVD?...even if the dealer was dumb enough to believe you? "

Simple
Buy the truck and register truck as-is , You add parts after like anything else
Snow plow , Dump bed , Lift kits ,oversize tires , Dark tinted windows ect..
The diesel requires no smog check anyways (in C.a) al least. Many , Many aftermarket mods are done to new cars trucks, Motorcycles by dealer after sale and state DMV or "FED's" are not involved.If dealer want to do it , Its no problem.

Examples: Dark titnted windows , applied by dealer and sold on new car, The tinted windows are not legal period , Buy a new Harley they change pipes ,Not Legal ect... you get the idea

 

[QUOTE=supeRobertduty]Yep, agreed

I dont think there would be any liability on the dealer if you told them it was for offroad use. Its the same thing as the none carb compliant tuners aviable now, they sell them under a off-road only cluse.

As far as the DMV, I know here in nevada you can register a 08 350 SD at 10002 lbs and anything over 10,000 is smog exempt so that problem is solved. The 250's would be a problem because they wont make it over 10,000 and out here they check for cat's on your truck when you smog them, i dont know if they will be checking for DPF's on the newer trucks.

 

Mine is already registered and ready to go. Problem is, I've not been able to get any part numbers for the pipes and ECM. If SANDDEMON can get back to that dealer and do a little undercover work, we'd all (maybe not all) be indebted to him. Numbers are usually stamped into the pipes, or if they haven't been hot, on stickers affixed to the pipe. The parts books haven't shown them yet as of about a month to six weeks ago.

 

I'll do what i can, i'll go down on monday and see what i can uncover.

 

I suppose it would be possible if your "STATE" did not inspect your vehicle when trying to renew the registration. However, if there is an inspection prior to renewal, then either it would "FAIL", or the MVD would then have to flag or label your SD as off-road only. Plus, they may actually require proof that it will be for off-road only...and that could be a problem...IMO.

Usually...the Govt will catch up...just takes time.

Great, another thing if you or they can come up with a VIN number, they can get the build sheet for one of those trucks and that build sheet will show the part numbers for that exhaust system and ECM, for that matter.

Things may get a bit interesting, now.

Thanks SANDDEMON.
