Ive read a few things about people suggesting a replacement wastegate and this fixing their bucking problem. If this worked for anyone can you suggest a nice aftermarket wastegate that would fix this problem? I can't take the bucking anymore and need to fix it so my car will boost.

Thanks for the help.
 
Atp is a good direct replacement. Cheapest option iirc, just keep in mind its set for 8 psi instead of 6. This was the first thing I put on my speed at 68k
