Passing emmissions in Mass

Just wondering if anyone has an answer to pass with a deleted truck in MA? I have a friend who can pass with his spartan but my H&S wont pass, Both of us have egr deletes and the Straight pipe exhaust. Im looking to get another 6.4 and would like to stick H&S due to transmission tuning but may jump to spartan if its impossible to pass without returning to stock every year. Any input or ideas are appricated.


Thanks Cody

IIRC MA does a readyness check. Is that what you are failing?

I couldnt tell you it must be my friend does inspections and when you have to plug into obd2 it just automaticly prints out a fail. So id assume it is the readyness check and pulls up the missing sensors?

I couldn't pass in WI with my H&S MM - EGR valve would not "Ready" itself for ODII test - Failed the first time. I loaded the lowest power level and drove around for a couple days. I borrowed a friends ODII scanner and the EGR valve would't change it's state - despite it cycling on low power. H&S must do something that blocks it's ability to change state, unfortunately.

I had to revert back to stock and re-install emissions to pass.

OP,

I would contact GH and see if they can make a tune that would "ready" the EGR before I gave up on H&S.

Unfortunately, since that was on the "Easy" tunes and those tunes do use the EGR, I doubt Matt could do anything....it's worth a try but my guess is it something within the programmer that can't be changed...like you said.
