Immediately, within a couple of hours they found the cause of the rattle AND the issue thats causing boost restriction! Amazing!

Soon as they took the bumper off, they can already tell that the intake was the problem. They did a dyno run with the intake on and off. With it on, they only saw around 5psi of boost. After they took it off, they immediately saw 10.

The shop that worked on the car initially custom fabricated the intake so I gave them a call and they were surprised that it was causing that much of a restriction.

And now the rattle…. They chucked it on the hoist and found that the right cat is defective… something is internally loose. Been advised to do a warranty claim.

Will keep this thread updated soon as I get updates…
So are you going to bring it to a new shop or have the old shop fix the intake and get them to retune it again?

If I were you, I would just demand a refund and take it elsewhere. Seems like you've had nothing but trouble and dishonesty through this shop.
