Ford offers a tune that you would buy directly from Ford which is covered under a Ford warranty and more of a mellow tune. https://performanceparts.ford.com/part/M-9603-EX30
ZFG is a custom tuning company that is not associated with Ford. The tunes that they do can be from mild to very aggressive based on the fuel type and modifications you have done.
I am probably in the low 4's 0-60 and don't know my 1/4 mile times. I picked the 93 octane tune because of the engine mods and this is a daily driver and will never go to the track. The rear sway bar did make a difference in body roll but the strut tower brace was just aesthetics. Didn't notice any difference in body stiffness.
