    Also - are you running it open loop (as intended from Chevy) or with the closed loop (O2 sensor added) setup from Arizona Speed and Marine? /forums/images/graemlins/laugh.gif

    Because it isn't emissions legal. /forums/images/graemlins/eek.gif It was designed for marine applications, so they kept it as simple as possible.

    OHHHH YES!
    I am getting a RamJet350 fer me K5 by Summer 2004.
    I am just now starting to gather info along with $$$, Common Tax return, please be BIG!!!!
    I hate to hijack this post but if some one does know what type of loop is the best or prefered, open means no Oxy sensor right? any other components used in a closed loop FI setup that is not used in the open loop?
    And yes please tell us about the MPG (back on topic /forums/images/graemlins/thumb.gif)
