Thats odd because the T28 has one as std and its FAR better than any aftermarket dump valve that has ever been on the market to date...
As far as I studied the construction of the stock valve bulid into compressor wheel it lets the air out in front of the turbo - maybe it backs off through the MAF and that's why the car stals? I only know it runs much much smoother now, when on ligh throttle I can shift gears just like in any other car. It used to behave wird when changing gears or lifting of. It simply runs great IMO (exept that I have other problems with it all the time :-((( )
