I'd like to try and crack 600 whp and I'm almost positive that is not possible on just 93 Octane alone. Just a side note I measured my jackshaft pulley as 3.19 and supercharger pulley as 2.89. I was curious compared to the setup you we're running.

Did you buy your kit used? The stock jackshaft and sc pulley's are 3.20. So, your jackshaft is the stock pulley which makes sense as that's the one you don't want to change if you don't have to. They don't make a 2.89 so your sc pulley would be a 2.85 or 2.95 if measured correctly which means someone had to have changed it at one time. If that's the case, you should be running a 3" sc tensioner pulley instead of the stock 2-1/2" in order to take up the additional belt slack that going with a 2.85 or 2.95 is going to cause.
