    Problem with Riva Stage 2 SHO

    First off, this is my first post even though ive been on greenhulk for a couple of years and i feel like i know all of you. Now the problem. I installed a Riva stage 2 on my 08 SHO and took it out to the lake to test. It started up fine but when I gave it some gas it would barely move. I turned it off and tried again several times and still the same problem. hopefully its something simple, any help would be appreciated. THX

    I'm guessing you had the intake manifold off?

    Start with all the connectors- injectors, MAP sensor connectors, ignition coils

    Make sure the manifold pressure sensing line is connected as well, along with pilot air line going to the BOV.

    Check that the FPR is set to spec.

    Probably nothing serious since it just started acting up after the install. Go over that thing real good and see if you find something.

    I actually left the intake manifold on, i didnt see any reason to take it off plus i didnt want to screw anything up. I forgot to mention that i also installed the Riva power cooler,i doubt that could cause much problems. Tomorrow after work i plan to check all the connections again to make sure i'm not missing something. It sucks, i was all excited to see what the new mods would do and this happened. Thanks for the reply BPnta.

    Gotcha. Thought maybe you installed the manifold upgrade too. Good luck, let us know how it goes.
