22psi

  1. 3 Litre ZD30 DI Engine
    Hi guys installed a boost gauge in my 04 GUIV after getting flat spots on acceleration on the highway to find it boosts up to 22psi (too high?) then quickly drops back down to 10psi while still under load...and is also having the oil light come on every now an then but goes away if turn car off...
