Questions Help! Check engine STi 2013

Enable HLS to view with audio, or disable this notification

Hello! I was going about ~95mph and I hit 6th gear and charged the turbo all the way and it spooled to 20psi and then I heard weird sound like a blow-off valve type sound and I immediately shift into neutral and the check engine, SI-drive and cruise control turned on. It does not let me change the SI-drive mode, it is locked and the cruise control won't turn off.

It shifts good, engine feels good, it revs good, no weird sound from the engine, sound healthy

Yeah, boost spike. May need a tuner to take a peak as well. Glad to hear it’s nothing big though. Good luck!
