Is there a 55-60 lb and a 60-65 lb siemens/mototron injector or are these the same part? BTW,your in the 9's with these? :eek!: I have a set of these and want to clarify,thanks.9SECVSIX said:I've installed a couple sets, there the best working injector i've seen with the stock computer, used Bob B chips from Fullthrottle. IMO you can't go wrong with these 60-65#injectors.
