I want to replace the 3way solenoind boost control valve that fits 6mm ID hoses. What is available? The stock boost control valve on my 1997 Saab Turbo is a bleeder type valve. The bleeding contributes to boost lag.

I want to eliminate boost lag while maintaining ECU control. I have an aftermarket ECU that provides a high degree of integration between boost, fueling, and ignition that I want to retain so manual boost controllers and stand alone EVCs are out of the question. The bleeder valve seems to be the heart of the matter.
