    Jesus could you clarify the fuel system setups please, I already have the VT11 injectors on my ski as part of the stage 2+ setup so I’m assuming if I added the cam with the correct map I shouldn’t need any other changes to the fuel system ? For example if I already have the VT11’s I won’t need to change out the fuel pressure regulator as well ?

    Correct....


    Anyway, check the library in this link : https://www.maptunerusa.com


    I made that website to try to help and give you guys a more complete info about all the tunes available. If you dont see your setup there, but you see a file is close to, then we can make it happen making a log file with AFR, etc ....


    For more info just send me an email: jesusg@rivaracing.com

    Hey Jesus
    I thought I'd ask here as it might help some members down the line, I'm doing this stage3 plus cam on a 300 just waiting for a few bits that are on back order.

    https://www.4-tecperformance.com/ind...oducts_id=7468

    The question is, in this kit there is a RRFPR the same as on the Riva site but in the link to the library of tunes the tune doesn't call for one, I have ordered one, would it be correct to run it?
