I have been slowly getting my car ready to be tuned professionally and my latest bit was re-routing lots of hoses and wires. Anyway. After i did this i went for a drive and took a quick look at my gauge and saw 20 PSI!! After a few experiements i found out that the wastegate functions normally.

My second experiement took the hose off from the tee between the turbo nipple/wastegate and put the manifold line there. Alas my wastegate is holding at psi. But i have no BoV (compressor surge blows). Its either one of two things.

The turbo nipple is blocked or giving an innaccurate amount of psi

OR...

My BOV is leaking super freakin bad at the port. In low vaccume the BOV does leak but in boost it holds fine.

Thoughts? Ideas? Advice?
