    How you know your tune is spot on...

    You know you've got a good tune when your engine runs perfectly from a cold start with your MAFS and O2 sensors unplugged. When you can no longer can tell if they are connected or not, pat yourself on the back....job well done. Try that on your factory tune.

    I know that's only half of a good tune with regard to fueling, but a major part.
