Is it a mass air or speed density system? I heard speed density systems dont adapt as well to mods as mass air. Thats the only thing i can think of. I have an E303 cam also and it runs fine with a lot of low end torque.

Nevermind, I didnt see the "92" part, so i guess it is mass air. Um, are you sure you got the cam timing right? Maybe you put it in retarded, that would explain the bad idle and torque but more upper RPM power. I dont see why the fuel system would need mods, if it was fine before, i dont think you should have to change it, besides if you werent getting enough fuel i would think you would feel it in the upper rpms not the lower rpms.
