I currently have Isspro Boost, Pyro, and FP guages. My boost guage does not react until 10 psi. Do you guys think it is the guage or another problem. I am wanting to get new gauges and I am looking at Auto Meter. Does anyone have any pros or cons on any guages and what the best is to go with there is nothing wrong with my Isspro gauges they just look a little outdated to me. And the boost guage is tempermental. Can i hook my isspro egt hardware to a different guage or to they require there own controller?
