I also have a Ferrari Daytona spyder with 6 dual throat Webers and, while balancing 12 velocity stacks is time consuming, it does run smooth once warmed up but it doesn't compare to the smoothness and balance of the DFI. Don't get me wrong, I love the sight of 8 velocity stacks on top of 4 dual throat Webers (not as nice as 12 but still very nice) and if authenticity was the goal, ie, a McCluskey Daytona coupe, that would be the way to go but with a SPF Brock/Shelby Daytona coupe authenticity isn't the goal, driveability is. Roush programs/maps the DFI and all you have to do is install it. I suppose it could be better, anything can, so once the warranty is up and, if you want, you can go into the program and remap it. However, Roush already spent a lot of time sorting it out so you have to ask yourself if you really need to. You can go in before the warranty is up but then you'll void the warranty. My car lights up every time, even when cold, is smooth through the entire RPM range, is driveable in LA fereeway stop and go traffic, driveable at low R's, great on the track, smooth right up to the rev limiter - which comes far too quickly it revs so fast. So, having driven both set-ups quite a bit, I have to admit that the DFI is far superior on both the road and the track.
