I think what happened last year, just before storage, I took my Z to my favorite oil change place and they had a line up, being impatient, I drove elsewhere, and the guy working on my car has an extra set of wastegate plugs. It kinda makes sense cause my boost was acting up at the end of last year. I will never let a stranger work on my Z again.

Car feels great at only 8.5 psi - the turbo spooling thru shifts is sooo enticing! Great kit! thxs again Sasha!
