    what s/c are you using. I believe the 50 injectors are only used if you are running a rude or c kit. You need a 42 lb injectors or the rising rate regulator. But no to the ecu and valve train upgrade that is for wanting to run higher rpms past the factory rev limiter.

    You are going to want to use whatever the aftermarket ecu mfg suggests.
    IF the s3 injectors happens to be the same as what you are currently running, then yea your good.

    i would check out the sticky at the top listing mods with speeds to see if any one else is running what you would like to run. IF you dont see it there list it here. and if someone has it they can chime in.

    You can not run 50lb injectors with a stock ECU without running a Rude electronic fuel controller to take fuel away.

    You run 50# injectors with a Riva ECU because thats what it's mapped for.

    You don't mention which supercharger you are upgrading to. If it's just a Riva pro series (stage 3) supercharger then you can run 42# injectors or a Rude rising rate fuel presssure regulator with the stock injectors.

    If you are running a X model charger, Rude Charger or C kit then you will want to run the stock injectors with the Rude rising rate reg.
