I also have a P3D+ with PUP. I ordered mine shortly after the free supercharging option (with referral) ended, so I don't have FUSC right now. However, I would love to get $5K back instead of adding FUSC if that is possible. As questioned by stvrobinson, what is the best method to initiate this? Call or write an email? Do we just mention Elon's tweet as the source?
