my aplogies if i used the wrong forum ...ok heres the deal i just bought the quadzilla and am ready to hook it up but would like to keep my edge ez so first question is does anyone know if they are stackable or not and second question if they are how would someone go about stacking them ...ie which parts connect where?.....thanks in advance everyone

The adrenaline would do everything the ez will plus a whole lot more. They will both hook into the map sensor and both would hook to the com connector under the hood. So I would say no they are not stackable.

Not stackable and like W+F said ...... just go with the QUAD
