    Have a few questions about tvs1900 and magnavolt system

    I jsut purchased a tvs1900 magnacharger. Im supposed to use the magnavolt system but do not want to cunt and tap wires and such. My understanding is this is simply a voltage increase for the stock fuel pump. Can this be tuned out so I do not need to use the box.

    Thank you .

    you would need to tune your vehicle in all aspects, increasing your fuel pump delivery is not tuning.

    MAF transfer/ or Speed Density
    Ignition Advance Adjustment
    Idle and Startup parameters
    Injector swap with calibration

    at minimum is what you need to do.

    best of luck

    I well aware of that .. its not going to tune itself haha, guess I should be more specific.

    Is that ALL the magnavolt does is increase fuel pump voltage ? And if so is there a table of somesort that I can use to increase the fuel pump voltage ? If not is there a formula to modify injector tables to simulate this ?
