I think 12.4 is very close to max performance with stock turbo. Maybe 12.3 but that would be very hard to do without cheats))
Don’t think couple of degrees decrease in iat is worth the price of a tuned heat exchanger.

standard factory airbox is the best for now
the car feel more responsive than using open billet intake
