i had a question,just curious if anyone would know,its an Apexi boost gauge,and ive never had this problem with it before,but the needle usually moves around the gauge very smoothly,but as soon as i hit boost hard,and its usually past the 0.5 bar,it starts shaking as its travelling up higher.i mean it doesnt stop halfway or anything like that,it still goes up fine,it just doesnt go smoothly.im not sure what would cause this,i checked all the connections,and the car runs perfectly,so i dont know.thanks
