Message	spool and i hear what sounds like a whooshing leak when im driving and trying to accelerate.. which is why i brought up the recirc valves earlier... I am thinking it is loosing a large volume of air until it can build enough pressure to seal the diaphram shut. I had sport 500s before this and they were loud, im not sure how loud the GTX28xx should be, but they are not as whinny as the sport 500s so its hard for me to tell if the turbos themselves are actually spinning as fast as they should be... wondering if valve overlap could cause me to not be forcing enough gas past the turbine to get it to spool.
