Unhappy Power Problem

Guys need your imput or help. Put a LPE 74211 cam in my car, had it tuned, and only put down 305hp 310tq to the rear wheels. Car has no torque till 4k rpm and peaks hp at 5700. LPE said that the cam might be advanced and to check it again and that it should put down a lot more low end torque than i'm making. Put the LT1 extreme duty chain on with cam . The car revs extremly smooth and feels very strong but track #'s showed otherwise. quikest e.t before cam cam was 13.14 @ 103. With cam quikest e.t so far is 13.14 @ 103mph. Car runs consistant mph but not time. Would eppreciate any help or assistance to get right. I chose this cam cause I'm in Cali and still need to pass smog. Air/Fuel was 12.7to 13.0 across the board with no drop in timing and zero detonation. Force Fed picked up 30 hp on tune alone.

Car 1996 SS # 667 A4
