I did, it's just that the TPS can be problematic even if it seems to test out ok. I and others have had it happen before.

You may be on to something with vacuum leaks, they're very common and can cause really weird problems. I found the most help from a tool that plugs the intake and has a pressure gauge mounted to it, you can pressurize the intake with the adapter that's on it. I tried a few different methods of finding vacuum leaks and none of them were a fourth as effective as doing it with this tool:

You'd want one of these two for the best results:
Boost Leak Tester (Gauged)
3" Diameter
With Tire Valve Adapter
$20 + $4.60 shipping

Boost Leak Tester (Gauged)
3" Diameter)
With Male Compressor Coupler
$20 + $4.60 shipping

And here's a DIY option that you can modify to make work for the '7:
