My car has been going into limp mode at high boost levels and RPM's when WOT. Goes away when i restart the car but once i get back on the gas above 4/5000 rpm it just falls flat on its face. i have a 2008 n54 FBO. Here are my codes from the jb4 and what they mean as far as i know:

2C31 - Dp fix apparently needs adjustment?
2C6B - Lambda Probe behind cats - no idea what that means
2C32 - Cats again?
29E1 - Fuel mix control 2 - no idea what that means
30FE - Ecu boost over target - Because of a leak? (I run map 2 or 5 normally)
0000 -
0000 -
3100 - Limp mode took place - you dont say...
30FF - Exhaust fume turbo low side (Boost leak normally)?
2F9E - Thermic oil lever sensor (I had an oil leak) FIXED
29D0 - Misfire cylinder 4? - il try a coil since plugs are new
00F1 -
2431 -
0008 -

any suggestions or prior experiences or knowledge of the codes would be greatly appreciated

Notes:

All plugs replaced 3000 miles ago
Injector and coil 1 replaced 1000 miles ago
Oil Leak Fixed Last Week
Intake Valve Walnut Blast done last month
