2005 MC SS SC boost adjustable ?

my parents just bought a 2005 MC SS SC , we had a 2001 SS and traded it in, just wondering if it is possible to adjust the boost on the SC'er when my mom drives it she doesn't need the power and would rather save some gas..
but when me or dad drives it.. i'd like to pump it up lol

its called swapping pulleys,..u can buy different size pulleys...but it wouldnt be easily adjusted liek you can with a turbo with a blow off valve , so either A. deal with it or b. get a different pulley and give it some more boost;)

so no adjustable screw to raise or lower boost pressure.. ? though supercharges had that =(

nope...thats turbo blow off valves that ur thinkin of also if u get a nice cold air intake for the car...it will def be alot more responsive, along with a nice cat back exhaust and the car will actually feel better, most likely get better gas mileage

if anything because it's not my car , i would rather the sc'er be less powerfull.. the car eats through gas.. other than changing the pully, is it possible?
