I'm digging into my Gen1 and looking for some good tunes for a VEC3 to start with. I noticed that on the base tune, I'm running lean (13 - 14 A/F). It seems that with a N/A tune, the fuel add needs to come on early (<2V on MAP) vs a boost application. Also, how agressive to get on timing advance is an interesting question. Since most of the tunes I've seen are for a SC app, any N/A tunes would be appreciated. I've got heads, 708CAM, Gen2 injectors, ported intake, headers, CAT-back.
