Could you elaborate? I have never heard of losing power as a result of BOV location. It's only open under vacuum, so I don't see how it would have any effect on power?

well, i think im right,im procharged and have a pressure release valve..could be a bit dif with a bov..but a friend of mine has a tt g with his bov's where urs are,a local shop recommended he move hem since they are releasing alot of hot air into his intake and engine bay..they told him hes losing a bit of powe(as im sure u know colder air=more power)..i could b wrong but im just going by word of mouth

This is the first I have heard of this...whats wrong with OEM? I always try to use OEM parts whenever possible.
I have no idea what whp it is putting out. I am on a stock block so its only running about 6.5 psi. The stock 245 rubber will spin every time when the boost hits in 2nd on a dry road in a straight line. I wouldn't be surprised if it went high 12s at the strip.

Actually the pipe just clears it. I can still get a filter wrench on the end of the filter. Once it is unscrewed it comes directly off. The hard part is that I now have to remove the undertray every time I want to change the oil, since that pipe is in the way. That involves about 20 or so fasteners

What does a BOV do? When your throttle closes it causes pressure to build in your intake trac because the turbos/SC have pushed the compressed air into the intake track when the throttle closes it no longer has anywhere to go. The BOV releases the excess pressure so you don't get compressor surge in your turbos/supercharger.
PS don't allow that shop to even change the oil in your car if they don't know what a BOV does they shouldn't be working on FI cars.
