If you want port injection then you have to step up to the Holley HP or Dominator ECU. There is a big price jump when you do that. If you need some help with an EFI decision contact Rich at FAST Man EFI. Rich is a member on here but he doesn't check in on a daily basis. Rich is a dealer for different EFI vendors and he has installed hundreds of systems over the years. He tunes a couple hundred EFI cars a year so he has seen most everything.

For a street car I wouldn't worry about port injection vs. throttle body. For a race car the port injection can be helpful. For a big power race car, especially something boosted then you should go port injection with either a HP or Dominator ECU. Anything in the four figure power level probably wants to consider getting rid of the distributor and using coil packs. Of course, I ignore all those rules when I did the EFI system for my street driven Duster!
