The correct way to do it is to install a fuel pressure gauge, install the pump and watch fuel pressure at idle. If its too high the regulator has been overrun and will need an aftermarket regulator. Adjusting the global will set the tune correct at low loads until the injectors are opening enough fuel to the engine where flow is reduced and the regulator can finally keep up. when that happens, you are now running lean because the global is backed off. You can tune it out but it is just masking the problem.
cause brad is running 10's on the stock one that is how he can tell him to keep the stock one.

personally I say if you have the cash just get an afpr. it's just one less thing to worry about
