Re: pullies and voltage kit for n/a
the ecu flash will do a lot more than the pulley. the pulley, imo, seems to help out at accelerating when at really high speeds but not so much from a stand stand still. the ecu flash works across the board and it is very noticable. i use the voltage thing- seems to do what is advertised (which is very little)- not really worth the money although i see you can get them fairly cheap now.
