Hello,
I have a 1969 Camaro with a Shafiroff 540 Ultra Street Edition. I currently have the FAST 2.0 Sportman system on the car and am in the process of switching over to the Holley system with multiport and injector dynamics injectors. I am looking forward to the results. I have not been a fan of the FAST system so far. I know alot of this has to do with tuning. In my area, I'm not aware of anyone who tunes with FAST, yet many folks are tuning with the Holley set-up. This is something that you may want to keep in mind when you need help dyno tuning the car. I am also switching to the Vaporworx returnless set-up and removing my ricks tank with Aeromotive A1000. The vaporworx system uses a fuel pump controller to throttle the fuel pump, along with a CTSV pump.
