Let me start out by saying hello to all. I found this site off of farmtruc's sig in the LS1Tech forum and I thought that I would check it out. It seems pretty cool and I hope to incease my knowledge about the 5.3L in my truck. I will be looking forward to you all sharing your knowledge with me. My truck is onyx black with neutral leather interior. Current mods are UPD intake (clear smoked) and a SuperChips MAX Micro Tuner. As of right now, I am waiting to save some money so that I can buy an exhaust for my truck by the end of the year.
