Well, Ford made it impossible to do any kind of timing adjustments unless you chip it, so we found another way around it. You may want to adjust your fuel if you are adjusting your timing, if your not getting hp gains. Its very criticle that you do that w/ a air/fuel meter while doing the fuel adjustments. Dont want to detonate that motor at high rpm's!!! Trust me ive seen some goof-ups by not adjusting the fuel while messing w/ your timing.
