A fuel pressure gauge here is going to be your best friend. If a tuner performs work without having one he/she is leaving one of the best available diagnostic tools in the tool chest.
If the fuel pressure falls when the car goes lean, the pump is too small (or not enough power getting to it.)
If the fuel pressure remains high but the injector duty cycle is over 100%, the injector is too small.
If the fuel pressure remains high and the injector duty cycle is low, then the power enrichment/fuel tables/etc. needs adjusting.
As far as the power wiring goes, if you are going to use a relay and shorten the circuit, a 12ga wire is more than sufficient. The wiring harness that is supplied by Rick's is not a VaporWorx part.
If you have one, can you post up a photo of the top of your tank?
