Has the F1 injectors been released for the 325/600 engines yet? I am running DDP 100HP injectors that were supposedly custom built for Piers Harry, but I don't know for sure. Anyway, I like them. They make good power and run smoother than stock, but I was reading on DDP's website and they recommend not running pressure boxes with their injectors and F1 says theirs are built for extreme pressures. So I was thinking of changing them out for a set of Flux 3's. Anyone using these yet? Will my SP66 handle them?
