I had a Procharger Stage 2 8 rib and had nothing but problems and got rid of it after months of going back and forth, uninstalling it and reinstalling it looking for gremlins and through 2 tuners the inability to get rid of mid throttle surging. Some guys have had completely different experiences where they run great with zero issues - but a whole group of us were having that issue and couldn't get it resolved a couple years ago.
I did a Whipple this time and if you want a zero issues kit - Whipple is the way to go. I just put one on a buddies car a week ago too with some pump gears and they're simply awesome. IAT is 20-30 over ambient driving around and less than that under boost. My procharger measured IAT at the inlet, not the intake manifold. So the comparison isn't apples to apples at all. But I think the intercoolers for both do a TREMENDOUS job.
On my centri setup, it made great peak power, but I had to really rev it up (3500+) and drive it there to feel it much. When it was WOT, and above 4k, it would wail like a banshee. On the other hand, my Whipple, off idle, you know immediately you've got more power, particularly the thicker torque curve. On the dyno at 2500 you step on it and it immediately goes over 500 torque to the tires and stays there or higher the whole pull. The centri built to torque as RPMS climbed but the hit was unimpressive unless you were starting at 4500 rpm. Disclaimer - I never waste gated my centri - but that seems like a combo of the best of both worlds. I've no experience waste gating them but building boost like a twin screw can't be a bad thing.
Completely different designs doing the same thing - creating manifold pressure. Both are a journey - let us know what you go with!
