This could be it too.

4)the botched install has crossed my mind. As has the solenoid. I don't think it is the dv+ either and it is my preferred choice over the turbo smart. I was getting a bit of flutter mind with the dv+ but no boost dumping.

Its odd as it only does it once it warms up. On my last tune I didnt experience it.

So in your opinion which one do you think? Or could there be a boost leak that could cause it
Did you guys remember to use all of the O-rings on the charge pipes? It's hard for me to put my finger on it if I didn't do the work on the car, haven't seen the logs, and haven't seen the ISTA diagnostics.
