    <font color=blue>Keep it! Initially, it will be more money and work to get running, but multiport fuel injection (its not throttlebody) is far superior to any carburetor. It will run better at any angle, run smoother, have more power and get better mileage than a carb.

    You mean the FI setup and brain from the vortech motor? I would keep it myself... if you decide to sell it give me a pm. The port injection is a nice setup but you may need to do some major mods for the VSS, security, and for the tranny aspects of the ecm.

    Keep me posted on it. It all depends what resources you have available to work with ecm. Try giving a local chip/ecm guy a call and get a price quote before you make a decision. I'm not sure how much programming you can do with those programmers that thiose use for mods. Also there may be some elctronic savey tricks like with the VATS systems on some tpi ecm's.
