I looked at that Bosch bypass valve at the Saab dealer last year. It
was awefully tiny. I didn't think it would help enough to be worth the
effort. OTOH, a bypass valve from HKS, TRUST, or one of those other
Japanese tuning firms is very serious. Those things can flow some
serious air! They also suck some serous $$$ though :-)
