I put in a pearable.net ecu and the car was idling fine and intercooler lines today. Took the car out building boost fine. Went around a turn and hit the gas and it isnt guage is still reading 10 psi. But i cant feel it checked the lines and they all seem tight. Could the waste gate have gone?

 

external or internal?

 

charge pipe off the turbo to the intercooler clamps were loose and boot was off the pipe.
