hello i have a 91 s13 silvia and its totally stock except hks intake and hks exhaust, but it runs 10psi instead of 7psi which is stock amount what could be wrong? it dosent have a boost controler just boost gauge and the gauges vaccum source is the right place. Anyone know why it does this? the car also has hesitation when giving it gas quickly istead of graduatly even though it spools up quick when stepping on it still hesitates.
