weak statement.

when saying something like that you better point out the changes in pressure that the pump delivered over the RPM range vs same setup with the high pressure pump. Because leaning out could be due to so many reasons, such as: not big enough injectors; crappy fuel pressure regulator; crappy tune of the setup; bend fuel lines; hell even not big enough power wires to the fuel pump itself .... and more.

but fuel is always good to have, so it wont hurt to get the high pressure pump. Some high-impedanze injectors dont like higher pressure though, wo watch out
