PCM Diagnostics & Tuning - 6ls help

Im needing someone to tune my 6ls I'm in Mississippi and can't seem to find a shop to do it! anyone know of somewhere or someone that could help? I just don't want to pretend like I know what I'm doing. Even with a wide bade I'm still kinda iffy

Thanks

you may want to copy this to the carbed thread as well. a few guys using this with the squirt but almost all the carb guys use the 6ls or msd 6010......

Thanks I'll do that
