Well I wanted to run FRPP injectors so I e-mailed and called Steigmeier to have the 80's re-sized... They say they can re-size any injector that is out there, so I sent them the 80's... 4 days later I get a call from them and they looked at the injectors and they can not re-size them because they are a single oriface injector... so now I'm picking up a set of Bosch 105's... :smash:
