Message	The stock injectors on my 90 TT Stage 3 have become unserviceable. Should I upgrade to the 555 injectors? It has a ECU listed as a Motorsports Auto part no - 11-2975. Also has HKS exhaust and powerflow airfilter. The [ www.courtesyparts.com ] lists the Nismo 555 injectors as needing an ECU upgrade and the parts guy said the Stage 3 ECU should be good enough for the upgrade. Does anyone know if theis is true? The other choice is to stay with the stock injectors. Really would prefer the upgrade to the 555's. Where is a good source on the 555's?
