Hey guys i dunno the exact benifits of this it's just a thought theres a vacum line on the stock FPR now one disconnect it plug it. As far as I know it should maximize the fuel pump allowing it to exert more fuel now this could shorten the life of ones fuel pump put it does result in a slight pickup..also doens't trigger the (CEL) I know adjust the Throttle Cable can throw the (CEL) once a certain idle is reached...Now this wouldn't really do much at WOT but gettin to it would feel a little nicer also for those with a manual, when you downshift you would have a better pickup no drop offs... Also noticed a slighter higher rumble out from the exhaust (catback) this is justa thought..I dunno ifi would suggest for long periods of use though this was just something a friend showed me on my car while i was bored waiting to get my turbo lol which i still am...
