We solved this problem on the sprintex kits with using a factory MAP sensor, but on the edelbrock you can't do that as the flange is different. The d-box will smooth out the signal and reduce the rich spikes which adds a good 15-20 hp and smooths things out. While we though of making a similar product, for what Bill charges for it I can't justify it, so just go for it and grab it. We've dyno'd it and showed those same gains they advertise

The D-box is tuner/tune independent. (but of course you will be tuned if you have the Edelbrock kit installed)
It's just the guys at @
DeliciousTuning came up with the solution. As Mike stated above, it corrects a MAP signal issue that is specific to the Edlebrock kit. Just buy it already!
