OH wow, that adds an entirely new dimension of thought to what I'm doing with this. Thanks so much for all the great advice there!!! I had considered going with MPFI but I kinda want to stick with...

Six Shooter, I couldn't agree more with on the thought that an ecm shouldn't limit horsepower. I may not know a lot about this stuff yet but I just can't see how the ecm could have anything to do...

Now I got it, just wanted to make sure on that. As far as upgrading to the new style injectors would there still be concern with whether or not the 7427 could support the impedence of 4 injectors or...
