TA had fuel issues starting with just a cam change on the original 180 hp motor, so I know how that feels. And as HP increased kept having new fuel issues.

Have you ensured there is enough valve spring pressure? Maybe not enough pressure to control the valves at high rpm. I never really experienced a distinctly noticable "falling off" but when I checked my springs they were under pressure. Switched them and saw almost 3 mph gain.
