I'm being facetious -- I mean that the octane boosters are not regulated in any way shape or form, so use at own risk.
That said, I wouldn't count on them to do anything especially good OR bad (other than drain your wallet a bit).
Seriously, if anyone here buys their new Z and thinks the dealer topped it off with regular, the best thing you can do is drive around gently (i.e., no flooring it, no redlining it -- not a great idea if breaking in a new engine anyway...), burn through 1/4 to 1/2 a tank, and then top off with high octane.
Hell, if you can find it, some Sunocos have 100 AKI at the pump. Half a tank of that plus regular will get you where you need to be (although I believe fuel blending winds up being not quite that simple in terms of effective octane...).
That's a much better way to go than adding a couple bottle of octane booster, crossing your fingers, and driving however you would normally.
Oh, and lookie what I found...

Remarkably, a few of them added a point or two of RON (although, keep in mind that AKI is the average of RON+MON... actually, a good rule of thumb on RON to AKI conversions is RON*.95=~AKI value -- example, our car requires 96 RON or 91 AKI, 96*.95 = 91.2), most added less than a point.
Still not going to be very helpful on a tank of 87. Siphon or gently use up, top off with high test. Done.
