Fault Code P2C57

Searched but could not find any related info..
During a hard pull, at around 240km/h reduced engine power warning came on.

I checked it with Cobb AP and the stored fault code is P2C57 , does anyone know what this is ?

I had FMIC and charge pipe installed today and switched to stage 1+ aggressive map. During WOTs it felt like DSC was kicking in , except that it actually was not. And while coming to a stop RPMs dropped to 450 - 500 and then up to 800 - 1000 and settled at 600 a few times (all while in gear)

I had no problem with stage 2 aggressive map by the way.

I will do some logging , meanwhile would appreciate any input regarding this fault code.

How did you fix it ? Could it be that something went wrong with the installation of FMIC and charge pipe , loose connection maybe ?

Well it hasn't happened since the track day!! I have order a new charge pipe though... Possible also need to check the stock piping wasn't damaged on the change of FMIC !!!
On day to day driving it doesn't happen so I haven't been to concerned about finding cause, although I should...

Started the car today and no more reduced engine power warning.
It runs smooth, no weird rpm flactuations when coming to a stop.

I forgot the AP at home and could not do any logging but boost seemed to building fine during WOT (in 3rd gear till 6th) , car ran as expected.

It does not seem related but could this all have happened due to bad gas ? The only thing I did after the warning was fill up at this station I regularly go to. Previous fill up was at a station I had never been to.

This is a boost leak code and is basically the same as a 30FF on the N54. In order for it to be set, there are several conditions that need to be met, so its much more common to see it at higher RPM on high speed runs. I would double check all couplers and clamps, then try to verify all vacuum/boost lines as well as the diverter valve. It could be a small enough leak that it doesn't cause a drivability issue, but still throws codes during hard driving.
