I'm running 8.5 PSI on my Paxton HO kit right now (essentially the same). I did have the 11 pound pulley on there that comes with the stock HO kit but I was pushing just north of 500 HP to the wheels. Like you I have a daily driver so I grabbed a pulley that comes with the entry kit safety's sake. I don't think you went over this, but is it an intercooled setup?
In the future you will want to look into an intercooler, especially being in GA. It gets hot as hell under the hood and I have an intercooler, your IATs are going to be through the roof non intercooled. But you will be fine with a conservative tune!
I am going to get one, but I want to make sure I don't stress the motor until I can strengthen it.
edit: My uncle lives in woodstock.
also, care to school me on bypass valves? Do they come with the kit or are they purchased separately? I'm pretty sure I'm getting one but if not, I need to know.
Im not sure how it works with a non-intercooled kit but the intercooled comes with one. THe bypass valve works off the vacuum of your motor and connects to the bottom of the intercooler and to the intake tube, then a small hose runs to the intake manifold. When the motor feels load it will close the bypass valve and it will boost, when normal cruising or decel the bypass will be open releasing the pressure, it also works to relieve excess pressure and to prevent compressor surge (when the throttle body closes and the air has nowhere to go but backwards towards the blower which can damage it) I'm pretty sure bypass valves are only used with higher boost pressures like with the intercooled kit. I'm just not sure how it would be utilized on a non-intercooled vortech system. Also the excess air is recirculated back through to the intake tube(close loop system), where as a BOV vents to the atmosphere.

The non-intercooled is set up like how you described in your first post about how they work, but the non-intercooled version is connected to the outlet of the blower leading to the throttle body, then to the CAI elbow as well as a vacuum hose connected fuel pressure line off the fuel rail, to the brake booster. The line from the passenger valve cover is also leading to the CAI elbow.
I wanted a blow through design because I wanted to vent it into the atmosphere rather than recirculate it back into the CAI. There's more to it than just unplugging it though lol
It's really just for sound reasons lulz I want that "ppppfffffssssst!" noise between shifts
this is what the non intercooled looks like , one end of the bypass valve is connected to a short piece of hose coming from the blue intake elbow . the the opposite end of the bypass valve connects to a hose leading back to the flat part of the Vortech intake . thus the re circling of metered air when not under load . when under load the by pass closes and you build boost
