Replacing FAST EFI on HP 383, with what?

I have never had any problem w/ the service techs at fast, contrary, it`s been among the best I`ve dealt with! They are busy, but have called me back when I couldn`t get ahold of them. I`m no wiring expert by any means, but their directions and a "little" common sense worked for me. I only have about 350 miles on my fast 2.0, but it has already smoothed out and running fine. I have changed the fuel ratio, and timing some tho. Pricy, but comes w/ everything, no need to go order other parts, or scrape up fuel pumps , or somebody elses regulators and such ! Very nice to tune, in the drivers seat ! Have heard that a lot of systems need about 500 miles on them to clean up .
I'm going t give the FAST sys a chance. It is being properly "tuned" with a new MSD disy. My race mechanic believes that the spark was the culprit all along. We will see next week. I will give the tech staff at FAST the benefit of the doubt. I may have caught them at bad times and talked to a tech that had little or no patience. For reasons mention before, I am still looking to go with carbs. Thanks for your support and your experience.
