Quick Fuel Question... Yes or NO

Everybody says my combination is mild and that I don't need some things.. to get my car running better maybe I should take off my 24# injectors, 75mm Mass Air and Fuel Pressure Regulator... I am hoping that it will fix all the problems I am having. I will return to the stock injectors, stock mass air meter, and stock regulator... Will my stock regulator work with my 255lph fuel pump?
 
Putting this stuff on is part of suping up your car. There is a problem somewhere. Figure out what it is instead of going stock. Will your stock regulator work with your 255 pump? Yes it will. So whats the problem you are having?
