Hello all! First off this site is great! Second this site is great! ;)

Anywho, helping a friend with a 383 tbi install, have most everything i should need to tune short of an aldl cable for datalogging. Truck idles well and runs "ok" but i know it has more potential. Basics of the engine build ar as follows. Flat top pistions with 4 7cc reliefs, Comp cam 12-249-4. Heads are swirl port with mild port/polish on exhaust side. Edelbrock tbi intake, 5.7L throttle body with 454 injectors. We arent looking to build a monster, see cam choice, just want to squeeze a lil more out.

So, my question is, which mask files do i use with this ecm-'6299?

Thank you in advance.
