Im going to eventually run about a 125 shot just on the track, would that make much difference?

edit: nevermind, i just saw that you use spray also

You may need a custom chip & dyno tune to get max power, but if you follow the manufacturer's recommendations for giggle gas, you shouldn't damage anything.

on a 5.0L FOX...I don't see the necessity for a chip...nothing a fuel pressure regulator and setting the timing won't take care of...however, a dyno tune would be nice...I am not convinced on the whole chip thing for our cars...however, GroverDill added a chip a while on doing a dyno tune and picked up like 30RWHP...he should shine some input on this...

Actually, a chip made a big difference on my very mild motor - we used it to change the idle speed, turn off the egr and thermactor functions, changed the cold start parameters so it starts/idles/drive-off just like stock even when it's 5F outside, changed the w.o.t. timing curve and leaned out the w.o.t. mixture to pick up significant HP on the dyno. Necessary - probably could get by without it; worthwhile - definitely for my car.
