Strange Boosting

[quick_silver_]

Ok I have a 95 gst and its boosting strange. Its pushing 16lbs of boost and when I get in on it, it boosts fine until 3rd maybe 4th gear when climbing the rpms. Its like fluctuating or something. It is like pulliing and stoping pulling and stoping like im letting out of it. It has a blitz dd bov hard piping to the ic, and a cheap manuel under hood boost controller. Only thing I did was the bov valve cause it had a cheap ebay bov called the monster when I bought the car. Boost controllers from ebay also again I didnt buy. The turbo is a Td05H super 16G. I didnt buy or put it on either. Fuel is STOCK. Buyin a fuel pump next friday along with injectors. So anyone know what the problem could be??

I feel at times my car has the same problem.... it feels like it goes in and out of boost. Like it feels like it pulls and the turbo is spooling, and then it feels like its not. Kind of like it lurches while boosting in and out.

Anyone any ideas? The turbo is fine by the way.
