Ecu x wont read pass 19psi

Hi guys i just bought another imola S4, this one is a 4door sedan stg3 by AWE, i did some logs and it wont
Read past 19psi and the boost gauge would say 24psi, the car has a boost controler and i lower the boost to 20psi and would still read 19psi all across, i lower the boost again to 10psi and then it would read 10psi on the
Ecu x logs but if turn the boost back on to 22psi it will only read 19psi, any ideas of what it is?

Thanks guys

it's pretty hard to tell why that is happening..

it could be the sensor (unlikely), could be the MAP sensor offset in the tune, could be where you are relative to sea level.

One of my friends log his car and it reads perfect, he is boosting 22psi

Sounds like your boost gauge is off/wrong to me. If "it" (ECU-X) follows it down to 10psi & back up to 19psi, then my money is on a flaky gauge. Very rare that the factory map sensors shit the bed.
