holley 750 dp question

Hey everyone,

I have a peculiar issue I was wondering if anyone has a solution

I have a 408 4 speed . I had an edelbrock 750 on it then switched to a 750 dp. The DP is about 2 years old. The DP is much stronger from a dead stop. Accelerated hard . But when I have it floored out it seems to slow the acceleration compared to the edelbrock. it feels like I need to add another carb to get the top end to continue the acceleration as fast as it is when at a dead stop. . I do not have this...
