Only when at WOT through 1st and into 2nd, i loose boost at higher RPM's. at around 5 it drops to about 5psi. when i shift into 3rd it goes back up to 10psi.

If i dont gun it through first and shift softly, and then in second WOT it goes to 10psi and stays....

Any thoughts?

 

Fuel properly distributed at slower acceleration might look into new injectors I would say.

 

could very well be a throttle cut situation, or your wastegate is getting tired and doesn't like to hold boost, or a boost leak. without actually logging the car all we can do is guess

 

thanks for the reply. i figured it out a while ago though, it ended up being my dv. tear in the diahram.

 

glad to hear it was a simple solution, I always forget about the DV's. I replaced mine with EVO ms DV's a couple of years ago, a world of difference
