i was wondering if anyone knows or has experience using Cyberdyne's Blue Ice gauges? i read here and there of some using them but havn't heard much. they are all electrical gauges and consist of the following:

*boost/vac +/-23psi, Oil temp 70-260F, Oil pressure 0-80psi, tach 2-8cylinder engines 0-9990rpm, trany temp 70-260F, Air pressure 0-150psi, Fuel pressure 20-100psi, A/F ratio, ambient air temp 2-158F, speedometer 0-250mph, Water Temp 70-260F and Voltmeter 8-18volt.*

i know theres other boost gauges that go higher then 23psi, but i'll never be going past 15 or 18 i think so and it's not being used in the scion.
