I own a 2002 Chevrolet Silverado 4X4 4.3L V6 and was looking to increase Torque and Throttle Response? Maybe Fuel Economy with one of those magnetic fuel savers or a tornado? I currently have a flowmaster 40 seriers muffler with dumps, airaid intake, poweraid tb spacer, hypertech programmer and a fuel at home tips. I was wondering although I know about engine swap and forced induction, What products were out their to increase torque and throttle response when playing in the mud. I often go off road and would like any advice on products or tips to turning my V6 into somewhat of an off-road machine. Thanks, Steve *I have engine swap and forced induction coming in a few years once I graduate.
