Is my c63s in softlimp mode?
Hello I’ve notice some power loss in my 2016 c63s
i took it to the tuner and did some pulls in the bench. It used to have 631hp in engine know it only had 561 its stage 2 with down pipes
if I look at the chart the curve looks wery weird
I get p010812 and p2a0d12 fault code sometimes intermittent after a wot pull and sometimes I get a CEL
top curve on the chart are from before under is from now
sorry for the bad quality

Yes i believe that also. b28/7 map sensor reads 990hpa engine off but only 280hpa when engine is on and idling with live scan
yes actually just on low boost and light acceleration but When I’m floring it my boost gauge are at max the whole time

A little update. I’ve noticed that one of the o2 sensors behind the turbo on the downpipe was loose so I tightened it and the car pulls much better then before now. But I still get p010812 fault code and sometimes it even throws a CEL not always. But I’m going back to the tuner tomorrow maybe he can correct the tune
