    I wouldn't keep trying on a new engine. Pay someone for a base tune if you have to before trying to start it stalling it rich or not giving it enough air. You really don't want to be overly rich on a fresh engine.

    I take a look to your tune, you cannot use neural network on a heavy moded car like yours.
    If you still want to use it (what I not recommend) follow this thread :

    but I don't think you will achieve anything correct, neural network is for stock cars or light moded cars ( CAI, headers).
