· My truck is SLOW!
Hey guys, I have been lurking around here for awhile and finally decided to join. I have a onyx black 2001 Silverado extended cab truck with a 5.3l. I don't have many mods on the truck right now but I am working on it. I am hoping that you guys can help me out in that department. As of now here are my mods, UPD (clear smoked) w/ AFE filter and a Superchips MaxMicroTuner.
