Does anyone know if you can stack a BullyDog Box (Made by Vanaaken/Peformance Tech) which plugs into the Fuel Pump Control module and a Power Edge comp box which of course plugs into the MAPs and Data link connections. I haven't punched the Pump wire yet. Just wondering if the two boxes were compatable before I completly retire the BullyDog box.

I've heard of people trying to stack timing boxes. I'm not sure about the results, but I wouldn't do it. The timing would be way to much in my opinion.

 

Ive done it. Van Aaken with Comp. It runs good, dont know how many HP it adds. It is too much timing. When the engine is cold it clatters bad under load, would not recommend.

 

The older style fueling boxes that did not change timing (they only increased fueling through the pump wire tap), can be stacked with the VanAiken type boxes (they only connect to the pump main wiring harness and sometimes the MAP sensor). I would not stack two boxes that both advance timing.
