I appreciate the add to the group. I've been researching 3rd gen ls tuning and stumbled upon this forum. A little bit about myself. I've been a heavy equipment mechanic for around 20 years now. I really enjoy fabrication work. Currently I'm working on a 2003 single cab shortbed that is a 4.3 v6 truck. I pulled an lm7 and 4l80e out of a truck to convert mine to a v8. Looking forward to learning more on the tunning and modifying of the factory computer.
