ok first thing is first. your boost gauge does not read how much boost you are pushing. there are 2 sides on the boost gauge. -20 -15-10-5 0 5 10 15 20. that does not in any way tell you how much psi your car is running. if you have your boost set to 5 like me, and if you hit the gas it will go all the way to 20, telling you that you have reach 5 psi. if you have it set to 14, and hit the gas it will go to 20 telling you it has reached 14psi. the point of the boost gauge is not to tell you how much boost you are under as in 5psi or 10psi or 14psi. the point is to tell you when you have reached the amount of psi that your boost is set to. anymore questions or if you dont understand, pm me and i can give a better explanation.
