Yes, I have the Dynatek injection system on my Superformance. (thanks Stentor).
Mine runs great now (although I did burn out the coil recently)
A couple of things about EFI. First, you have to get around the "Voodoo" of EFI. The system is simple to work with once you get your panties hiked up. Second, you MUST address fuel delivery. My fuel delivery was based on the stock SPF gas tank maintaining fuel to the A1000 pump which it can not. If you buy the DynaTek system, I recommend a surge area that maintains constant supply to the fuel pump. This can be done several ways. But if you have 600 hp on tap and sticky tires the gas in the tank runs away from the supply to the pump with the stock SPF tank. I now have that resolved.

Now on to the DynaTek system. They currently do not supply a turnkey system that has a FAST ECU, or a wideband O2 sensor. My system has the Pantera ECU, and it has worked great for me. Now Dynaforce is supplying an Accel ECU, and I do not know anything about it.
My car starts no matter what (I just had to update the SPF start switch, but other than that), and idles without issue. Throttle response is "right now", in accel and decel, so you have to be on your toes when down shifting.
Dynaformance was Dynatek. They have been through a bunch of changes, facilities and personnel. Some of the key people I worked with when we (Keith Craft and I) ordered this system are gone. Finding out the level of support, what ECU, and your ability to tune would be key if I was buying another system.
The wow factor can not be beat IMO, it never fails to turn heads at any show I am at.
