Thanks Lenie .. All those fireworks you hear today was how I felt when I got the brand New Fast XFI . It has the ECU and all the harnesses.
I have two intake setups one is a Victor E with setup for EFI. It has a Holley 1000 cfm TB with all the sensors. The other is the World Motown manifold set up for the Dominator that came with the engine. It would have to be setup for EFI. I also have a Fast 4500 series TB it flows up to 2000 cfms. I would really like to use the Motown and Fast TB But I was told I might loose low end drivability. Anyone who tunes these let me know if this is a bad idea and I should stick with the small TB my motor makes 610 hp. As always thanks .
