    RR ECU AND RR IMPELLER

    I've been told that we can run the new (higher boost) RR Impeller with stock injectors if you have the RR ECU, with the head being stock, stock compression, and so on. Just bolt-ons like a riva stage 2.

    Is this correct? Has anyone tryed it?

    And if so has the AFR been safe?

    Thanks

    Yes you can, but its always best to add a margain of safety by running the 42# injectors.

    OK Cool.

    They dont make like 40lb injectors.

    Because if it runs fine with just the 42lbs and the stock ECU or with the RR ECU and stock injectors then to be on the safe side you most likely don't need the 42lbs with the RR ECU.

    Runing rich is safe but its holding you back aswell.
