After checking out the amazing TSRM, I'm pretty sure its the wastegate. I am going to check it with a Turbo Pressure guage, but I am pretty sure the rod connected to the wastegate valve is stuck open. My question is: in the TSRM, it says to replace the Turbocharger assembly if the rod doesn't move. What exactly is included in the turbocharger assembly, not including the turbo, because the turbo is fine? Thanks.
