You can't have two boxes tapping the pump wire at the same time.

If you stack two wiretap boxes, you have to decide which one you want to run as the wiretap and which one will only talk to the computer.

For example, if you have both a Edge Comp and a TST. You want to tap the wire with the TST and have the Edge only plugged into the computer. The Edge will handle low end fueling and TST will take over for higher boost.

If the Quad box you were looking at plugs into the Data Link Connector (by the lift pump), then it probably controls timing. In that case, you only want to run the Smarty on even settings so you leave timing advance to the Quad box. If you run both adding timing, you can end up with too much.

 

ok no the quad box only hooks to the map and pump wire and the apps. so dont hook up the quads pump wire and hook the map after the edge map sensor the quad box is only a 65 hp box the edge takes care of the timing and the hot unlock lets me fuel to 3200rpm is there another way to fuel just a hair past 3200? thanks for the help AggieJustin i dont want to sound stupid but in ur sig what is a 2low kit?

 

never mind i found out what a 2 low kit is sorry i dont have a 4x4 just curious what happens when u do have 2 boxes tapping the pump wire at the same time

 

I'm not that familiar with the Quad boxes, but what you described sounds similar to a TST.

If you don't hook up with the pump wire for that box, you will not get any benefits from that box. The connections to the MAP and APPS just read signals, it is the pump wire that adds performance. Are you sure that is only a 65 hp box? Generally you can do 65hp without a pump wire tap.

 

yeah its the xzt not the xzt+ all the other ones require data link connections and my edge is already plugged in there what box do u recommend stacking with the edge juice or if both require a data link connection do u just leave the smaller box unplugged? so far i have only found one that dont tap the pump but i connects with the data link and that was the xzt+ im not set on a quad box but i am set on stacking my edge juice with another box and then later adding the smarty again thanks for the help

 

also what about the diablo power puck it connects to the factory pump harness or will that be dthe same as having two boxes tapping the pump wire

 

The Juice is a 120 hp box. When you're stacking boxes, what you are looking for is one to take care of your low end fueling and another to take care of your top end. The Juice can take care of both if you want. I think the only thing that you could really stack with the Juice will be the Smarty. But since the Juice adds timing, you'd be restricted to running only even levels on Smarty with no timing.

The other option would be to remove the Juice tap at the VP44, then you could run a TST. But this would turn the Juice into nothing more than an EZ and wouldn't really be cost-effective.

What is the goal you are trying to get to with stacking boxes? Through any stack with the Juice, I don't see you getting over the 120hp gain that the Juice gives. The only thing you might gain is a different fueling curve on the way to 120.

If you're just looking for some additional revs (past 3200) you might have to switch to a box beside the Juice.

 

ok well what box would fuel past 3200 i origanally wanted a tst powermax 3 stacked with a smarty but i got a really good deal on this edge from a friend of mine thats why its on my truck now i also have the 150hp nozzles but i want the truck to do more that cant be the end of my options with this truck im open for suggestions if u have any thanks
