    Have you pulled the plugs to see how they look?

    Which tune exactly? What fuel octane?

    Remove spark plugs, inspect.

    Install fresh spark plugs if the removed plugs do not show any problems.

    Sounds like a bad battery connection. Put a volt meter on it while it is running to make sure its charging. Probably not enough energy to fire coils.

    I would take a look at the map sensor and be sure it is connected completely and also that the hose/fitting it is connected to is correct and in place. Perhaps it did not get put back in place good after the ribbon delete mod. Be a good idea to check all electrical plugs for the sensors.

    Check injector harnesses, number 4 IIRC is a problem on the newer engines. Broken pin or wire in the connector.
