Apologies if this doesn't apply, but I had this thought -- back in the late 1960s, VW started putting throttle positioners/dashpots on the carburetor to avoid that momentary burp of fuel when letting off the gas pedal allowed the throttle plate to close suddenly. Does the Holley have provisions for something like that? Even though the main goal was emissions, seems like it would be good for FE too.
P.S. Maybe this is something your vacuum gauge and TPS sensor would help you avoid, I dunno.
