if your tune turns off the rear o2's, it will NOT pass. just went thru this with my car, and matt did as well. the o2 readiness monitors will not set, and it will not pass emissions.
need more done to the car for the charger. if its a 5 speed, it def needs a different trans before a charger, def needs lower control arms, 1 piece driveshaft, exhaust, etc
