I'm going to say that you need a fuel pressure gauge too. In fact, aside from the pyro, a fuel pressure gauge is probably the most important one you can add. Nothing will kill your injectors quicker than low fuel pressure....
I run a pyro, boost, trans temp and fuel pressure.
I got my gauges from
GOS . He has always had good prices and excellent customer service.
