My AUM boost pressure appears to be low, as the car is running on standard map at the mo and I have a FMI also a cold air intake with the cone down at the bumper, I think all the extra pipe work and the larger cooler is making hard for the turbo to fill it all and keep the pressure up, the car is maxing at 5 psi then dropping to 3, my question is, would it be okay to fit a bleed valve to bring the boost back to the standard pressure again? Thanks.
