Hello everyone.
I'm loosing 3psi of my target boost by the end iof the pull. My tune us set for 20psi tapering to 15-16psi but I'm ending with 13psi at 75% WGSC
Full bolt on with no wast gate rattle and new vacuum lines. Awaiting a smoke tester next week sometime.
Here is a log ror reference any ideas please let me know. I'm thinking solenoids as they are original 136k miles.
NO 30FF CODES
