I bought my intercooler off a guy (2 years ago)... who does alot of racing with Volvo's.. he mentioned something about using a Saab wastegate.. it is a standalone knocksensor activated wastegate. Has anyone ever heard of this thing? He said he used it on his racecars. It has its own ecu and can be put in any car.

Can anyone direct me to any more information on this thing? Or someone confirm/deny this thing even exists.

Anyone own a turbo Saab?
