Ka24det weak below 5200rpm - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a 97 240sx ka24det, and at 15 psi it doesn't really pull as hard as I think it should until around 5200 RPM where it seems like it flips a switch and really goes balls out. I hit full boost around 3300 RPM and it holds steady. I've done several boost leak tests only to find no leaks.
Mods are: 740CCs, Enthalpy, z32, precision sc50 w/ .48 a/r turbine on RH mani, and tial 38mm.
Any ideas?
