I found one in the forum that mentioned the same thing a little eariler but Im trying to get a good Idea on anything it could be. I changed my stock clutch to a stage 4 competition clutch and also replaced the clutch master cylinder. I also had the fly wheel resurfaced. Now originally I thought it could just be the clutch that was making my car jerk at WOT however after reading another post it brings up a possible boost leak or fowled spark plug, Im trying to get a feel for any other possibilities, any help would be greatly appreciated.

 

check your vacuum line to the FPR, thats what caused mine to jerk at WOT

 

A tune i ber probably couldnt hurt

 

If it's not violent, and just feels like a split second puff of no power and happens kind of randomly at WOT it's the plugs.
