Ma has the same testing, but only on 2008 on up trucks do they plug them in to test diesel....certain it wil catch up to all years that can be plugged in soon or later.

Not understanding why use that trans, when everyone else is adapting the Allison to the Cummins? Is that what your truck was built with? Sell it! Put the money towards the Allison. What you save on not needing a custom one-off adapter will finish paying for a max-built Allison.
Dare-to-be-different is cool, but can get very costly, very quickly, and then continue to add costs. Best to just go with the flow. ( Says the guy converting a sports car into a trailer-tower )

The Cummins 6.7 is certified until 2012. My specific engine was used in a MY 2010 truck. My truck is a MY2008.

If my Cummins 6.7 was equipped with all its emissions equipment, my truck would have no problem passing an emissions test anywhere in the country.

Obviously the twin turbo setup negates passing the emissions test in some jurisdictions. But nothing stops me from putting the engine back to stock should I need to.

I will be deleting the EGR and DPF for the time being. I may install them at a later date.


I can only speak for Washington state but your truck would not pass here. When they connect to the trucks computer, it has to be the exact configuration and eng code the testing computer is looking for. Anything else will stop the test before any measurements can even be made.

Same with Nevada. It would be a square peg, round hole deal with the smog stations. You would have to fight the DMV for some sort of relief.

Same year or newer, I gave CA BAR (CA Bureau of Automotive Repair) a call and spoke with a smog rep, he said as long as the engine I drop in meets the CA requirements of my stock engine class then it's good. 6.0L Powerstroke was 2003-7, CR Cummins was 2003-7. My truck chassis is stamped Mar 2007 but the engine data plate is stamped May 2006. Even though my stock engine has an EGR system, I am not required to drop in an engine with the same components, all the engine needs is the plate riveted to the front of the case that says "CA emissions legal"

Diesel engines at the federal level are certified when the engine was built, not the chassis. Federal gas engine emissions certifications are based on the year model of the chassis, not the engine.

States, however could be different, but state law shouldn't trump federal law.

I think he was pointing out the " but state law shouldn't trump federal law " comment CARB who employees my cousin BTW, is one power house in not only the biggest auto market but any thing to do with air quality. Even the fireplace's are regulated in new home construction not to mention little things like lawn equipment engines. If you look at any states new laws regarding air quality standards, it was CARB related. Sorry you already knew that I guess
Does OP live in Cali? If memory serves me right from other posts, I think so.
