Well i am new to this board, but i am not new to the gm ls1 world. I was a GM Tech for the last 4 years. 3 months ago i got my first gm though. 1999 short bed silgle cab 2wd silverado ls w 5.3 liter. within 2 months i turbocharged it with STS and had the PCM programmed by Nelson Performance. Also i upgraded it to 42lb/hr injectors. So i guess ill be browsing and posting here to keep up with the LS1 world.
