Boost pressure regulation control range not reached P0299

[hishamswidan]

Hello all ,

i have Golf 5 GTI ,

TFSI / BWA engine with Ko3 turbo

it's already tuned to stage 2 , car run and pull fine but when reach above 5k RPM ,the p0299 fault pops up (Boost pressure regulation control range not reached)

i checked the 6 maps for ( LDXRN) and the maximum number : 208
any hints about what cause this issue ,maybe KO3 can not handle this boost or there is another thing ,
