Hello I have 2 fault codes on my c63sP010812-The intake manifold pressure sensor has a short circuit to positive. There is a short circuit to positive.

and p2a0d12

I’ve have checked with live data and 253 B28/7 (Pressure sensor downstream of throttle filter)
reads no atmospheric pressure N/A

and

560 Signal voltage of component

'B28/7(Pressure sensor downstream of air filter) Reads 0.6 Volt

My car has no power above 5000rpm it has a flat power curve and 560hp stage 2 in the bench
it had 620hp before in the same bench
