i got a 04 lightning boosting 12lbs. with a couple of mods.... for about 2 weeks ive been hearing a weird sound as if the supercarger is studdering...it sounds like a turbo on a diesel 7.3 liter with a straight pipe...when i accelerate a little hard off the line its when i hear it...any ideas what this might be?? also i dont feel any loss of power

 

I had a similair problems but with the bearings in the snout check it out if they are the bearings in the snout of the blower or see if the rotors are touching each other

 

With the truck off take your hand and wipe under the supercharger snout if you have a bunch of black dust it could be just your belt slipping.

God Bless,
