Yep, here's the truth- you're curious whether an 
@ZFGracing  baseline tune is the same as Joe-Bob's tune which is cheaper $.  I can definitely see that if you want to save some money you can buy something else.  If you thought for a moment, you'd see it will never be an apples-apples comparison.  Just go buy whatever you can afford and are happy with.  The question you should be asking is whether a custom tune that makes 440 whp on 93 on a completely stock ST is worth the extra money to you. Whatever baseline tune he's using is just to look for logging data to see where the limits are- as well as to accommodate those who've added other upgrades.  If you've done no upgrades and don't plan to, buy a less expensive tune and enjoy it.
