I have the old style va box that just plugs into the vp-44, I was thinking about buying the edge ez to stack with the va. Or should I just buy the edge comp and just have one box.

 

buy a comp you will only see about a 10 to 20 hp change at the tire. And a little more smoke

 

So by stacking two boxs I will only gain another 10-20hp over what the one box already makes.

 

Yes that is what I have found on my truck on the dyno

 

hey trash. aren't you worried about blowing your head gasket with that hx-40?

 

Big Robin I blew that head gaskest runing a comp and a Hypertech truner. I don't run that combo anymore. not even on the dyno

 

The best stack combo Ive heard is the TST fueling box with the Edge EZ timing box.

 

DO not stack plug in boxes!

i.e. do not stack any of the following with eachother.

Van Aaken PnP, BD PnP, Edge EZ, Edge COMP...or any other rebadged unit sold under a different name.

If you want to stack boxes, the VA/ Powermax, and the Edge EZ/Blue Chip stacks work well

 

whats wrong with stacking those ones? i'm running an early stile Van Aaken and the early edge 3 stage amp box with no problems.

 

A VA and an early Power Edge Three level box are stackable since the Power Edge does not plug into the CAN.
