boost gauge
I own a evo IX. Everything on the car is stock including the three gauges it came with; battery voltage, oil pan temp.,andturbo boost.Can anyone tell me what the 1.5 on the boost gauge is equivelant to in psi? When I am at peak boost it is reading around 1.0, it never makes it to 1.5. I was told the stock boost is around 20psi, is this correct?

RE: boost gauge
When I reach peak boost it will read right in between 1.0 and 1.5 so I guess my turbo is creating about 18.4 psi. I guess this is normal considering the spike is 19psi. Does a stock evo 8 and evo 9 create the same boost? Will an aftermarketBOVkeep my turbo's boost from tapering?
