Exhaust brake problems
 

Hey everyone! ive always owned a 5.9 but just bought this 2008 6.7! i love it so far but im having an issue with the exhaust brake! idk but sometimes it comes on hard and really slows the truck down an other times its slugish and u cant hear it or barely feel it! then yesterday it got hungfor a few secounds after i got back in to it! 2day i checked the codes and it showed p1451. help me out yall, it also goes into the shop for a recall the 31st. thanks

1451 is particulate filter performance code I'd start by deleting that mess because even if you do fix it. It will come back eventually that could maybe be causeing the problem and the egr doesnt help our turboes any could be causing it to get stuck / and or not work properly

What can I do if I can't do the deletes due to emissions? I've had the same problem with my exhaust brake coming on when I get on it. I've noticed that my truck has become a lot more sluggish. I've had some tell me that I need a new turbo but nobody out here in Colorado seems to be familiar with the 6.7's

If I had a 6.7 I'd straight-pipe the cat and DPF do the EGR delete. By straight piping, I mean don't just remove or gut them, but actually install pipe through it. It will flow better that way and as long as they see them there and it is not setting any codes you will pass emissions.

seems like the guys that run hard out on the open road has less problems. i live in wv where you cant run like that. after i deleted my truck runs good. i will never put that stuff back on. if somebody makes me the truck will go down the road to a new owner. its a cryin shame they put this junk on them. as the dealers say , use your exhaust brake and run it like you stole it till you get dpf and egr delete

well now im getting the run around! i took the truck to the dealer ship told them all the problems bout the recall, and exhaust brake! they say i need the 2 micron filter! get it outta the shop. 170 bucks for the new filter an housing which i think dodge or cummins should have 2 pay 4 since its there mistake. drive down the road an guess what. exhaust brake hangs up. it spools up but no holding back! grr im gettin ill. call the service guy back an asked if he cleaned it or what. he said he 4got come back well have to blow it or desoot the turbo! ( how to they do that?) and got it outta the shop yesterday, still no better than it was. grrrrr nothin looks like they have touched or cleaned or even turned a wrench on it! WHAT SHOULD I DO! HELP!

Gibby, which recall are you talking about? I haven't gotten a recall notice about the exhaust brake.

no the recall was 4 reprogramming the dfp something it came out in april 2010! but the exhaust problem was another issue

Tell them your not sure what is wrong that it will need to be driven, and insist on being in the truck for the ride. then when it's "fixed" tell them you want them to take you on another test ride. Also be ready to start seeing trouble codes now that your dpf program is "fixed". Lotta people having problems with that. heres just one
