If your only getting 7psi with the wastegate line removed, then you have either a MASSIVE boost leak, which would surely be accompanied by a very loud rushing sound, or the turbo is faulty in some way. Without that sense line, your boost should rocket to something silly like 20psi, EVEN ON A STOCK TUNE! then the ECU will catch it and dump you into fuel cut.

Pressure test it up to 15psi and see if it holds, if it does, then your looking at a fault with the turbo itself.

Its not a Chinese copy is it?
this is what ive been trying to get at thank you!!

No its not a cheap chinese copy its brand new from from RP turbo

So... i should pressure test the wastegate to see if it holds 15psi?
