thanks for the link firebean. I'll pick one these up. My airaid is constantly making my BOV open when driving lightly. It's annoying listening to a fhump fhump sound when the truck changes gears (BOV opening). It's definitely allowing my turbos to build boost easier, but I don't want to over work the blow off valve. Hopefully the drop-in will keep the boost in check while allowing the turbos to spool easier. $35 is cheap enough to experiment.
