Good Afternoon. I am new to the forum and want to introduce myself. I'm from Western Colorado and I enjoy working on projects and tuning GM vehicles. I have a 2003 GMC Sonoma (S10) that I converted to a 5.7 L31 just over 5 years ago. It has 30K on the L31 and runs well. I had to take a break for working on it for a few years (Life got in the way) now I am able to devote time to various projects again and I am hoping this forum can be a great resource for information as I refine this project and hopefully start others.
