Or maybe you have clogged exhaust portions and a vacuum leak...i.e. bad converter/rotted vac lines?

not sure for exhaust i have ssac headers with no cat or resonator the only thing inline is some magnaflow muffs, and even so if i had a vacuum leak im not sure how i could get 4psi at idle lol

but the thing is could this be off in hptuners because my vehicle boost guage which i know is by far not accurate doesnt show any bars while sitting there

edit: oh and i just ported my supercharger and all the vac lines looked good
