Can anyone please tell me whats the cause of these codes:

P1101 fault code 594 input variables charge measurment.

P1249 fault code 231 boost pressure deviation below limit

 

594 input variable charge is p1109. Ask me how I know

 

Whats the cause of it?

 

Here are the relevant manual pages. Several possibilities suggested, although the one common to both codes is problems at the intake/throttle body. Weren't you the guy who had all sorts of problems with the AP intake kit?

Yes thats me, thanks for the attachment.

 

Still sounds like a bad leak. Boost leak test and/or smoke test. Use a higher pressure like 30psi or so...
