This is what I do after the IACV has been blocked off and intake pipe modified. Go into timing mode, adjust base idle via throttle plate, leave timing mode. Rev engine, to about 4500rpm, apply brakes to try and make engine stall. Test drive same test, real world. done. This my experience with SR's though and most had atmospheric BOV's.
