Still can't get a full pull, car goes lean up top not sure why yet.
Stock wiring from the engine compt fuse block to the FPDM won't support a whole lot of HP with dual Focus pumps due to the high current draw of those pumps.

When I had a D1SC with a 3.4" pulley and dual Focus pumps on my car, it hit 100% duty cycle @ 5400 RPM. I upgraded the wiring to the FPDM and it went down to about 80% duty cycle @ 5400 rpm, and hit didn't 100% until about 6800 or so.
