never had a bouncing idle caused by anything but a TPS( 10% of the time), or a vacuum leak(90% of the time). sounds like boost blew a line or a nipple off.
do you have paper or metal intake gaskets?( or maybe just silicon?)
Paper or silicon, i would check there also. or do a intake pressure test, as these dont seem to expensive to get the parts to do. just some homedepot fittings, guage, and some soap and water.

A pulsing idle is typically a vacuum leak, a few things to check:
Throttle cable for seizing, needs to returning completely
Turbo inlet duct for cracks
All couplers and clamps on intercooler
BOV for leaks, especially if it is aftermarket
Check your boost sensor, if the voltage is screwy it can tell the ECU all kinds of bad info

bouncing idle can be vacuum leak. one reason its more likely a vacuum leak instead of a tps: it started after you did a hard pull.
im going to guess that boost pressure blew off a vacuum line.
