I wish I knew how to get rid of the DPF without tripping computer codes. Any ideas? Can it be done?

Hey Mr.Gris! Thats pretty funny! When you blow the engine in your truck and you need my help to get it covered under the warranty, don't call me. I'll be busy laughing my a$$ off at you! :D

Sorry.............couldn't help it!

HotDuck,
On the 6.4's most guys are running the Spartan Diesel Tech setup - - DPF delete, 3 custom tunes, Dashdaq for monitoring and claiming up to 6mpg's better stock. I don't have a DPF setup yet, but its tempting. I'm sure there are guys doing to same for the new DMAX.

The new LMM DMAX will show it has been played with in the computer. i am sure over time someone will find a way around it. The exhaust has around 6 sensors pluged into it. It is common from most of the sites I keep track of that the mpg's su#k on the new trucks with all the polution stuff on them.

go to the dieselplace.com ,theres a computer programming software kit,you use that to bypass the dpf system and put in a regular exhaust system,but keep your stock exhaust sys,its worth $5,000-7,000
