As to the idle though, I can't say for certain how the upgraded bypass valve affected it, because the same day I cleaned out my AIC valve and throttle body, neither of which had been done in years. The idle was improved, but on my car, fluctuating idle has never been a problem. My problem was the RPMs would drop like a rock when I'd put the clutch in, especially after just being on boost. Sometimes it would stall, mostly not, but would always plummet rapidly to about 400-500 rpms before catching.
The improvement which I think I can attribut to the bypass valve, are smoother throttle response, especially when under full boost and then suddenly releasing the throttle. No jerks whatsoever. Before, in stop and go traffic, creeping along was geting to be a real pain, as no feathering of the gas pedal would keep me rolling without the herky jerky.
It's still no automatic Honda or Toyota, but it's pretty smooth..
