Trucks keeps throwing these 3 codes any advice?

P0238 - Turbo Boost Sensor A Circuit High
P0470 - Exhaust Pressure Sensor
P1211 - Unknown
this is all that popped up but what exactly is this telln me. i dont understand the exhaust pressure sensor i had put on an aftermarket exhaust but there was never any sensors on it before

Also its been putting out low boost around 18-19 psi at most and when its trying to put out higher pressures it flutters something awful. bad waste gate?

Sounds like your exhaust back pressure sensor tube maybe clogged there is a weight up in the tech section on cleaning this. The that if no change the exhaust back pressure valve in the turbo pedestal might be bad or the waist gate could be stuck.
