Is it the TPS?

[rbade12 at aol.com]

 I'll put my vote in for an intake tract leak.

Let us know what it was please.

Possibly TPS, but also consider possibility of a torn hose or loose 
clamp--suddenly "letting go" at some level of boost pressure. I 
assume your car is chipped? Have you looked closely at the throttle 
boot lately? A tear (near the edge of the clamp on the inner side you 
can't see easily) caused a similar symptom in my car. I detected the 
source of the leak with a pressure tester. Also, a split Michelin Man 
hose can sometimes "burp" suddenly when near the max boost pressure.
