How do I tell if I have a HFC fitted or not??? Without having the emissions tested. Is there anyway I can tell? Is it much much louder than normal??? Booked my car into Abbey for Thursday to get one fitted and it suddenly hit me whilst browsing the dyno thread. Some cars are running similiar power with HFCs fitted, so maybe I'm lucky or maybe I have one fitted already and wasn't told about it when I bought the car.
Please please help me. Don't wanna have to make the trip to Abbey to find out I don't need to and don't wanna mess them about either. Thanx in advance.
