Error code 32, only half boost
 

Hi all,
Friend of mine has a uk classic 1999 and he is having trouble with his boost..( only reaching 0.5 bar ). Been there today to clean boost parts with no joy so had a read on internet and decided to do an ECU reset and found it coming up with fault code 32, ( oxygen sensor, maf.). Please could somebody tell me if these parts would affect the boost.. Before it started to play up he had fitted a cone filter and a front mount intercooler ( could these affect the boost ) Many thanks in advance
