I just install Prosport Electrical Gauges and was wondering is the reading is right. I have 07 WRX, the picture below is when the car is in idle. Isn't suppose start in zero instead of -20? I believe all the wiring I install is correct. Anything wrong on using the supplied T?
When the car is on boost at about 4000 rpm in 3rd gear. It's only goes up to 5-7psi. I don't that is correct. What is wrong in my set up?
