I have an '88 full size w/5.0 e.f.i.I was thinking about changing to a little bigger injector.Do I need to get a different fuel pump or will a stock pump work?

If you havent done anything to the motor you may be doing more harm than good by putting bigger injectors in it . With bigger injectors it will be harder for the EEC to control the fuel air ratio . I believe stock injectors are 19 lb/hr and they will support up to 260 HP so unless you have done something to the motor to drastically change its output youd be wiser to spend your money on a K+N and a really good tune up .
