Dual Plane vs Single Plane Manifold with TBI

I have a SB with header and I had a single plane. When I put A dual plan on my engine my drivability went through the ceiling. If you are just cruising a dual plane is the answer. A single plane needs gears and stall to be really effective.

KINDA DEPENDS ON UR ENGINE SIZE AND TOQUE , STROKER BIG BLOCKS HAVE AMPLE TORQUE -----------dis regard caps , cant keep my fingers off of it .
