Yep, that's what I'm starting to realize now as well unfortunately.
Would you consider this conclusion correct? (this is open to all as well)
The reason we can't go with both the 9 PSI Pulley & Impeller Upgrade for the Stillen kits, is because each on their own would increase charge air temps to a level just below dangerous. Putting them both on would cause charge temps to sky rocket well into engine-exploding territory, and this is made worse by the fact the original Stillen design sees the MAFs installed pre-charge, so the ECU would never actually see the correct temps and maybe mitigate things by pulling some timing. All of this effectively is due to the original Stillen W2A design, more specifically the actual Intercooler embedded inside the Intake Manifold which due to it's small size is just not able to absorb enough heat before the charged air enters the engine. If someone wants to properly exploit the potential of the Vortech Superchargers, they would have to change to a traditional A2A Intercooler system which has far more potential to cool the charged air, making the option to install both a high PSI Pulley & Impeller upgrade safe/viable again.
Is any part of that inaccurate or need further elaboration?
*edit* I don't track my car and have no real plans to so it's just street driving with an occasional hard boot. Maybe a handful of times a year also take it to the local drag strip. */edit*

1). No matter how cool or how much of upgrades u do (pump,exterior heat exchanger) the heat exchanger in the manifold can only allow and cool so much fluids at one time l. This becomes an issue when u are pushing the car hard consecutively. Like u I upgraded to the Frozen boost prior to going A2A. What I noticed was recovery time was a lot quicker when I got off the throttle but when pushing the car hard I had the same issues..it's still ran hot and that narrows it down to the interior heat exchanger in the Stillen Manifold.
2) The interior heat exchanger in the manifold takes up a lot of room, which makes it an obstruction for the cold air being blown through the manifold.
Any upgrade from the Stillen is a plus and it should hold up til u can get on the A2A kit. Just be sure to give the car recovery time when ur tracking it (cool down lap) and don't do any upgrades (impelller/pulley). The Stillen kit is made to handle the power and boost it was designed for and nothing more.
