We use SC cams for street cars to put as much torque in off-boost as possible. They are a terrific improvement. 964 cams will slide the torque curve to the right a touch which also adds power up top.
As for fueling you are past what a Lambda laden -145 USA FD can handle. Don't know what the FrankenCIS is capable of but it can't produce more fuel than the FD will supply. The -007 mod is needed for that. If the FrankenCIS can work stand alone without Lambda that would be worth a try. I don't like add-ons that spray fuel in the manifold as the runners are not a tuned path to each cylinder so will not properly distribute the fuel. Yes they will work by just dumping gas but there or better ways to supply adequate fuel to meet the needs of the engine.
