I ran 42# injectors up to 8# boost with AFR's at 11.0 just hitting 85-90% duty cycle. You have to remember that the Carrera FPR runs the fuel pressure at less than the rated pressure for the injectors so your effective flow is less than 55#.
I have a single knock sensor mounted on the crankcase vent cover and seems to work OK. Given the choice, I would add the bridges and go with 2 sensors which is probably what I will do when I next tear down the engine. It is good to know you can machine the heads to fit the bridges which are inexpensive and not have to source custom cylinders.
