If i update my predator and raise the RPMS will it perform better?

what i mean is that it actualy had better accelaration before i installed the programmer it work good over 50 mph but from 0-60 i actually had more better accelaration on my stock tune just need help ive heard good stuff about thid programmers
i dont wana think the opposite

Predator u7151 did not make a difference in acceleration do they even work?
Not sure what's up but i think i had better acceleration from 0-60 before installing
The premium tune on my 04 4.6 f150
