Hello peeps, I'm new to this group, heard about it from a friend. I have a 2008 gmc Sierra 1500 4x4 5.3l. I love this truck, but I use it as a tow vehicle on the weekends to pull my race car, and I'm wanting to get a little more torque and hp out of it. Been looking at supercharger kits and not sure which way to go with it, nor where to get the best price. Any help would be greatly appreciated. Thanks in advance.
