code 34 turbo pressure
 

i understand alot about the way the ecu works but what is happening when code 34 triggers is it maxing out the fuel system, i havn't read the vf reading yet when it happens, i just shimmed the waste gate and runs steady 11 lbs but hit 13 at about 5 grand in 5th gear. when the code triggers its under load before the 13 lbs... any info would be great...
its 7m-gte with custom intercooler and other than that pritty much stock ,rebuilt bottom end and new head gasket
