Can you provide some specifics on the cam profile, how the setup performs on cold start, hot start, throttle tip-in, and part-throttle acceleration? How difficult was it to tune & did you have to use a dyno to dial it in? How or why was Fast EFI selected vs Electromotive or Motec? I have a similar engine configuration as this one, and I'd consider converting to an EFI setup if I could find someone who is unequivocably happy with it and would be willing to share their formula for success. So far the 4 or 5 people I have spoken with (or helped out) have spent countless hours trying to get their EFI to be smooth for street use. It seems as if most can get cold start, idle and WOT to work well, but have never got the "middle" perfectly tuned. Thanks for your response.

I guess I'm unequivocably happy with it. But mine's Electromotive.
Works great startup, idle, part throttle, decelaration, acceleration, cruise. Of course TEC has a means of using data logged during actual driving to update the tables to get you closer and closer to optimum tune. Don't know squat about FAST. With Electromotive, after everything was wired up, the brand new engine with brand new, never tried injection setup, fired right up with the TEC's base map setup. After that, it was a matter of drive, read, update, drive some more...
