allright i got a 91 integra b18a1, im pretty sure i have peak and hold injectors (stock), and i allready have a resistor box that came stock with the car, and im putting on 450cc blue top injectors on it, but im not sure if they are peak and hold or satured, does it matter? or is that just part of the program they run on?

i tried the search but couldnt fine what i needed

 

wait i think i just found the awnser in the new user facts , oh well, correct me if i am wrong that my car is peak and hold and the dsm inj. are peak and hold

 

You are correct, they are peak and hold injectors, and if your car already has the resistor box then I would say your injectors are peak and hold as well.
