What are some cheap things that i can do to make my truck go faster.?

its a 89 ford f150 custom it looks really nice and sounds awsome with the custom exaust and it acceleates preety quick but i want it to go faster cause im like all guys ha...it already has a cheap racing chip in it i may buy a new one and the peviose owner changed the gear ratios to make it accelerate faster.. im kinda new at trucks and v8 engines i use to have a ford probe gt with a v6 so its new to me/
