Boost,
My S5 has a ported motor, and this is exactly what I'm seeing. 2nd gear hits 11psi and then slowly drops to 5psi by around 8k rpms.

The statement I keep reading is that the turbo can't keep up - this makes no sense to me as the wastegate would completely close if boost pressure dropped below the target.

First gear is different for me, I see only 8psi of boost, which also drops to 5psi. Anyone have an idea whats going on here?
Best,
John

Stock ports with full exhaust is going to creep if your turbo is stock. Keep in mind if you have a FCD and are using the stock boost gauge to read your boost then you will not show any creep at all on that gauge because of what the FCD does.
