When I slowly rolled onto it I had no detonation. When I stomped on it I had detonation. Hopefully this is the issue. Edelbrock tech did not have a reason why this was missing.

Yeah something is definitely off if your getting 14 psi out of that 4” pulley and the stock 87mm throttle body restrictor. I don’t understand any scenario where the bypass valve, no matter how wrongly configured, gives you that much boost. If you are that’s certainly impressive
