My friend gave me some gauges to install on my car. He gave me a boost, oil pressure, water temp., and air/fuel ratio gauge. But when i turn on the car the oil pressure gauge goes all the way to 100 psi and it doesnt move it just stays there. Also the water temp. goes to 300 and stays there. What could be the reason that this is happening? Also im about to install my turbo in about a week. Do i really need these gauges besides the boost gauge?
