i noticed lately that when i step on this car above 5000 rpms the boost drops. it use to be around 11psi stock pulley headers with rear cats, sometimes i see7.5psi up top. changed tensioner and even sent stock pulley to griptec for extra bite. yet the car feels like its pulling. logged it with ndash and i have the aeroforce gauge not sure if i should try a mechanical gauge to see if that is different.

maybe its ok logged it this and logged map and that is on like it has been in the past maybe boost reads low on zeitronix ndash. its in the 24 25 psi/hg range and 22 psi/hg up top

Doesn't make sense. No way you boosting that high. That 24,25, and 22psi figures you can subtract about 14.7psi if you at sea level. So basically same psi boost you saw in your first post using your ndash.

sure it does did not say psi its read in psi/hg divide by 2.036
