    Volvo Penta GM 5.7 TBI low power at take-off

    There are no "chips" the motor is already putting out a fair amount of power. To put out more you need to go bigger with the motor, change cam, or you can add a blower..... All will require the use of MEFI burn and remap the ECM Drop to F4 props

    Everything done but low rpm at WOT. Distributor spring?

    What butchering? Other than coming with a fuel feed and most likely needing to be gone thru from sitting. I don't see any "butchering"

    12v boat hoist motor
