You don't need to run Q16 or expensive fuel, 110 octane is $6.00 a gal here, and It's only to get your car safely in tune then go to reg. pump gas. I tried a water/meth. injection 15 years ago and for my buck it's not worth it.
I tend to go for max. all the time, just as you started with 6 psi then felt the power of 15 and don't want to go back.
On a fuel system don't go cheap it's the most important part, or turn down the boost ! Holley has a new pump 12-700 that looks good.
