Took the car out for a quick scan before the headers/dp/rocker/pulley install and for the most part all looks good. . . except when I convert the kPa to psi it says I'm hitting anywhere from 15-20lbs of boost on an other wise stockish car. Am I reading this incorrect or should I be looking for a vacuum leak??
