Power Puck stack w/Edge Juice

[pblankenship]

I was wondering if I can stack a power puck with my Edge Juice? I have heard that if you get an older model that only plugs into the back of the injection pump you can stack it with a juice. Just a quick question, I got the juice cuz of the gauges and I got brand new for 380 bucks, I couldn't turn that down. Now that I have gotten a taste for cheap, I don't want to spend 400-500 for the EZ to stack with the Juice, plus I would like to be able to update if possible.

Thanks for the help
