Help!

Quick question. I did a pull in my car went to a stop light went to drive off my car was bucking pretty bad with every throttle input in the lower rpms. I pulled over check for boost leaks couldnt find any. I have it throttle it went into boost perfectly fine. The throttle has no inbetween its either on or off if that makes sense. If i were to give it little throttle to cruise nothing will happen. Its either give it alot of gas to speed up or no gas to slow down. Im thinking tps. Any other suggestions?

Cliff note: Under boost it works perfectly fine and pulls hard. with minimal throttle it bucks pretty bad. no crusing either on the gas or off the gas.
 
what engine in what car? mines doing the exact same thing and it makes for a terrible daily. i hope someone knows so i can figure out my crap and fix it too lol

Ive got a spare TPS if that happens to be ur problem :)
