lol ya i didnt wanna order one from toyota but im also having fuel cut at 4 pounds of boost. which it shouldnt do that at that low of a psi. so thats also another reason i was thinking it would be a good idea to replace the knock sensors. and no i havent checked the CEL codes yet.

Check your codes...your symptoms could be caused by many things. A boost leak is the usual cause though.

Knock sensors don't limit how much boost you run, the ecu retards the timing to save on possible engine damage from a code 52. http://www.engineblox.com/?p=65

^^ This is what I've noticed too (assuming you have a code 52 that is...). Though most of the time on these cars it's just the knock sensor wiring that could use a refresh with shielded cable.
