Where did you order you're PC5 it's hard to get one here in California ?No issues, just pull all that crap off. Keep the solenoid plugged in. Vacuum cap the throttle body. I kept that little roll over valve thing on. Figured it was a pretty cool thing to have. Just do it when you are installing the exhaust and intake. Pulling the plastics off makes it a lot easier.
Good thing you got the PC5 also, the 2021 doesn’t like the other fuel modules.
