Anyone did this? to make the pump run at a constant 12v? any improvements if so?

I just noticed that you own a gt4. In all honestly, you really don't need to do this mod unless you upgrade to a higher than stock flowing fuel pump...and as long as you are on the stock injectors/ecu, there is no need to do that.
The factory fuel pump in your car will work fine with the factory wiring. And the low/high mode probably helps gas millage, and to lower the overall drain on your electrical system. -------------------- 15PSI - 30MPG - Megasquirt Tuned

Ok then, thanks for the info  from more research I learned this was done when the resistor goes bad, as it would drop off voltage between the transition from 9-14, cause a lil bog down before it switches to 14, but I think it would probably cause a little over fueling at low rpm and at idle.
