So I just got my car back from the dealer...went in with hesitation issue and a DTC for a bad Bank2 EGT sensor....but tey also went ahead and replaced the wastegate since the tech said this was usually the problem with a hesitation issue on our cars. Now that I have it back...it seemed to be running a bit flat around 4k.

After driving a 4hr trip this weekend it seemed to go away and the car feels normal again. On my way home (another 4hrs) it still felt fine even at WOT. After I got home tonight I pulled DTC's again and found this code:

1 Fault Found:
17963 - Charge Pressure: Maximum Limit Exceeded
P1555 - 35-10 - - - Intermittent

------

I haven't logged anything yet so I figured I would see if anyone can point me in the right direction since I'm really not having any symptoms? Not sure what this code even means? Reading in the archive points to N75 valve?

Thanks in advance
