Some how this trick saved my a** tonight when the cops were doing their "part 2" at a RBT tonight. They were after a atmo BOV and they watched it while they got me to rev the hell out of the engine. All they heard was tsuuuuuuu from the turbo, then they were like that's ok!
Sometimes i feel sorry for them as they obviously did not have a clue, twice they looked over the engine bay before they asked "Where is the Blow off valve?"
My god they over looked the boost controller and solenoid, FMIC, POD, Exhaust, rim spacers, etc. Makes me think i could of had a high mount turbo and NOS kit and they still would just be after a BOV.
