Turbo timer removal

I also have a greddy turbo timer installed on my car, its non-functioning, it just shows me my battery voltage... id like to remove it, should i expect any problems just unhooking all of the wires?

Shouldn't be a problem. I would track down where they tapped for power and remove that wire and repair that properly to avoid any shorts. Removing the ground too should not be hard as well. Should just be bolted somewhere near the timer.
