boost cut

[crotty]

ok for a while now my laser has felt like it hasn't been boosting at all. In fact, I couldn't even hear the turbo spool and I'm dumped. One day I'm under the hood and I rev the engine and see the wastegate move! I then touch the wastegate and I am able to move it back and forth! I know this is not good so I take it off and once I get it off I comes apart in 2 pieces ( spring must have popped out). I put in another wastegate and start her up and then I hear the good ol' familar turbo sound. I take it for a test drive and right at 3 grand, I hear the car boost but then it bucks back and forth very violently. I'm thinking this is boost cut and that maybe it has something to do with my mass air. Or could it be fuel cut? HELP!

I have never heard of boost cut, but it could be fuel cut. I would get new plugs and wires first, then hack the MAS.

I have brand new plugs (Ngk) and brand new wires (magnecore). I already have the Mass air mod (honey comb removed). and I am running without the air can (open filter K&N). So what could this be? HELP!
