low boost?
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.

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.
