No top end power, need help

Hey guys, I agree completely on the timing aspect of his tune, but i'm a little puzzled on the last 1/4 of wide open throttle. I'm wondering if secondary side is way lean or way rich. Maybe even the opening rate is way off. Last time I saw what he described was on a Q-jet that the air valve was just flopping open on full throttle. I'm just bringing it up for conversation as i'm not a Eddy guy by any means....:D.
