my 1990 f150 5.0 litre is sluggish with canopy and trailer etc can I chip it up to get more power out of it how do I do that I have already cut out both cats, new cap rotor plugs wires fuel filter k+n air etc maybe a timing adj ? thx

 

Just advance the timing from 10 deg btdc to 12-14 , then put the money you were going to spend on the chip into long tube headers and custom exhaust , that will help the most , the chip wont help ....Lew
