Which DFI system to use?
 

I'm new to fuel injection but recently bought an Olds 455 that has been converted to fuel injection with Accel injectors and TPI style throttlebody. Which DFI system (Accel, Fast, etc) would be a good system to use. I don't plan on doing any racing just building a nice street car. Engine has also been converted to a distributorless ignition (Electromotive). Any systems to avoid?
