After getting tuned, will the X pass the OBD scan or do I need to flash back my stock map. I don't have any CELs. Thanks

 

That's a good question. I was just thinking about that the other day. Would hate to go back to stock tune just for a emission. I would also like to know as well. bump.

 

Ya, I was thinking about when I got a letter saying I'm due in June for one.

 

You should be able to pass emissions. Search for threads on MA and their new inspection rules. If your tuner tried to disable rear O2 or emissions related CELs then you may have a problem there. If they did the emissions force-pass then you may have a problem in that state.

If you have just been tuned and all emissions pieces are in place then no worry though.

 

I'll contact my tuner this week and ask. Thanks for the information
