ummm, are u stock?.. stage 3?.. bc to tell u the truth i had the same thing happen to me right before my cat clogged up and gm recalled it.. the m62 eaton doesnt really perform like that.. it actually tech gets inefficient somewhere around the 18psi-18.5psi range.. tested fact actually... so this just doesnt seem right here.. nor does it sound right.. when i get anywhere in the range of 18psi all u can hear is a whine from the supercharger.... urs just seems like.. "clogged"
