If anybody has any DH logs of a before and after that they could post. That would be helpful as well.
Besides boost, I mean.
the only time an upgraded bov (or bpv, bpv = recirc bov on this forum) will show a performance gain is if you are currently pushing more pressure than your existing valve can handle. this will cause it to leak and the air the engine thinks its getting won't make it there. a better bov would fix that problem.
if you dump air out of the closed system that has already been metered and expect to not have any adverse effects then you're a moron. after the air passes the MAF in this system it enters into a closed system.
a bov's function is to alleviate pressure that builds up when the throttle plate is closed so that the turbo doesn't have to fight hard to spin and damage itself. that's it. if the one you have is working correctly you will see no performance benefit.
I totally agree with this, at best you will not have a performance gain (rated in HP). But there is a benefit to be had for a properly functioning BPV/BOV, for all of us with the gobbler. When you kill the turkey this means that the compressor is not being stopped by the air trapped by the throttle plate closing and thus when you shift and then step on it again your spool is sitting there waiting for you, you don't have to experience lag again....
also note that some piggy back EMS's don't like a reloc-ed MAF (i.e. unichip). Having the MAF on the pressurized side will work for X amount of time but it will fail sooner than on the un-pressurized side
