I have a 91 TT that needs the injectors replaced. I can get the OEM ones for wholesale but the question here is should I upgrade to the 555's. I know that if I do this I also need to get the ECU reflashed. The car is pretty stock with the only real mod being a 3" custom exhaust. I plan on running higher boost once I get it back together. Do I need to spend the extra money on the 555's or should I just get the stock injectors and send the ECU to Jim Wolf for the added power? Any help as well as pricing would be much appreciated.
