Yes.

It depends on the specific emission requirements for your state/province really. I just recently passed MOT in England (like your standard state inspection). I made a bit of a write-up on it at fduk.org. You can see it by clicking this hyperlink if you are interested.

you can buy a used reprogrammed stock ecu here in the fs section

btw, i'm selling a M2 stage 3 ecu, dynoed 315whp at 13psi with stock cat in place

 

Just got my car dynoed today with PFC, made 236kw @ 11psi, very happy with that as I just have the usual bolt on mods
