What kind of horsepower and more importantly what kind of torque curves does a P1SC or D1SC Procharger make? My buddy is thinking about getting one and he has a 2005 Chevy Silverado with the 5.3L L59 (I believe the RPO code is correct) w/ the 4L60E trans. He's wondering about the torque and horsepower curves since its going in a 4500lbs truck.

 

that must be a flex fuel truck because the regular 5.3 is LM7 and the aluminum block higher-compression 5.3 in select z71s is the L33.

search for ranwalk he has soem dyno charts put up of a forged, stock displacement 6.0 with a d1sc i think

 

get the D1SC.
