Hi there: Looking for some opinions on stacking an old Vanaaken box which only connects into the VP44 harness along with an Edge Comp box. Pros/cons anybody?????? and what kind of power gains can a guy expect over and above just the Comp box by itself. Did a search on this topic and got answers on both sides of the fence, anybody have anything new to add???

 

Both boxes control timing and therefore won't stack.

 

thats rite,it will give to much timming advance,i tried the exact same thing with a old van aaken and a comp and it had good power till 2000 rpms then she hesitated and ran like crap.not a good idea. use the comp and sell the van akken.

 

TST with VanAaken(or any timing box), from what I've been told
