Do you mean modify it to have it hold more pressure or less? I do not think the relief valve opening is limiting your pressure on track.
My thinking is that having the relief valve open SOONER would allow you to run -50 or -60 weight oil, boosting high-temp high-RPM oil pressures while limiting pressures at the colder temps. It would essentially help "flatten" the pressure vs RPM curve.
In the reading I've done the last few days I did come across articles that talked about excess oil pressure 'washing' out the bearing surface.
