Does aftermarket heads and cams raise the emissions of our cars? And I guess that leads to my next question do we have the sniffer in dfw area or just the ses scanner? I've been thinking of getting both but want to make sure I don't have to slip someone a 20 to pass the car.

 

here in dfw, its the OBD2 test.

Cant answer about the emissions question tho, sorry

 

im sure it does, but its just OBD2, so as long as you dont have any codes, and you have all your emissions things you should be alright.

 

get it tuned with LS1edit and make sure you don't have codes.

 

ok cool, thanks guys!
