I can't turn my boost down below 18psi. I have a TA49 turbo, THDP, TT6.1 chip, and I am using a RJC boost controller. I have the controller as long as it can be with only 2 turns left until it falls apart. I presume the adjustable wastegate actuator I have is a standard version (see pic) and it is set per rjc's instructions. Anybody have any ideas? I am seeing some knock on my PL files and I'm sure the 18psi with 93 oct is as good of a place to start as any. I will attach some PL files if I can figure out how to attach them.
