    Damn, guilty as charged in the bold!
    Hell, I'm only 30 guilty as charged.

    I fully understand though that fuel injection is a completely different animal from carbs.

    Would like to thank everybody that posted for their advice.

    I think I'm going to go ahead and cough up the coin for the fast 102 and a tb to go with it.

    My goal is to get the most I can out of the 346ci I'm working with right now.

    Not so much the tb..as the maf or the lid and the bellows part.

    Yes and no...even with the opening restricted the design of the runners etc is where gains are to be had for the most part.

    How about eliminating the maf, and going with an SD tune?
