Jet size help

[Tom86951]

I am installing an hfs-4 system. I'd like help validating my jet selection. It's a 4 cylinder engine running 850cc injectors (one per cylinder) and I'll run up to 22psi boost. What jet(s) should I use? I decoded the graph chart in the materials that came with the unit, and the jets it suggest seem bigger than most people seem to be running.... Of course this motor does make a lot of power...
