If it has a black plastic MAF, you need to swap it with the aluminum one. All the SS EJ22T turbos used the aluminum MAF, even though it's usually called inferior to the newer ones.

When does the throttle cut occur? At what psi? Stock 22t ecu will give you fuel cut around 13 psi iirc unless you make/install a fuel cut defender.

I would check these sites out. The BBS Legacy is dedicated to the 1st generation of Legacys.

It cuts out after 2200rpm it has a vf8 turbo i heard it was from a jdm ej20g wrx but not sure. Its not so much a throttle cut as much as it wants to just die. It almost sounds like vaccuum hoses are trying to blow out of the intake instead of sucking in air but idk
