ok well my truck has been makin this noise when it is boostin it is at about 10 pounds until like 15 it sounds kinda like a sequential bov on a car is there somethin that kinda might make it bark or somethin at that boost and anything lower or higher it doesnt do it it is 26 pounds max boost also wondering if there is a place to get some sort of leveling kit cuz my back sits quite a bit higher thanx for any help

 

Sounds like the turbo is surging. A compressor upgrade set from GDS or HTT will fix it.
