Did you put the o-ring in the charge pipe at the throttle body connection? And the one at the BOV connection?

O ring at the throttle body or methanol bungs need to be tightened (they often come loose).

The meth bung plugs ship loose and need to be tightened prior to installation. I'd do a smoke test and start with there. If you don't know what that means I'd suggest taking it to a professional or spending some time with the search feature

Yeah, why do those plugs ship loose? That's a seemingly pointless booby trap that causes headaches for a substantial fraction of your customers.
At the very least, you could print up a note and throw it in the box.

Got the o-ring for the BOV installed? That alone can bleed off 5psi.

I wish I would have known this because guess what?? I finally solved my 30ff code.. a little nice note in the box would have been nice for sure.. It was a headache for sure but luckily all the parts I replaced like the boost selenoids, plugs, coil packs, were from FCP so lifetime warranty saved me but wasted time when it was just the meth bungs

With mechanics, expect nothing, check everything. And Never, Ever be in a hurry.

True that it was semi my fault too for not checking everything lol. Also my first CP that came with meth bungs.
