    New. Tuning a 5.7 blackbox for a 5.0 vortec

    Thinking about tuning my pcm to run a 305 until I get my 383 built. It's a clean a tight engine. Anyone have the parameters I need? Also I don't know which hp tuner I need. Thanks

    We only sell one device, the MPVI2+ so that is what you'll need to tune your vehicle's ecm assuming you are using an ECM that we support.

    Make sure to check our supported vehicles list to ensure the ecm you are using is from a vehicle that we support https://www.hptuners.com/vehicles/
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    You should be able to look find a stock tune for a 5.7 and 4L60E in the repository that'll be close to what you need
