FAST XFI Sportsman on my '73. It uses the same throttle body as the EZ 2.0 system, but the ECU is different - fully tunable, fuel & spark. I've installed EZ 2.0's on a few cars and they have all ran great, but I wanted to be able to fine-tune my motor to a higher degree. I also wanted a deeper understanding of how the various tables work. SO much nicer, being able to change fuel and spark characteristics from a laptop, rather than bent over a hot engine!
My LS tuning buddy sat in on my recent chassis dyno testing. He thought it was funny that I was only hitting about 46% duty-cycle on the injectors. I was putting ~315rwhp at that point, so that means the throttle body should support 600+rwhp.
