Tuning an L83 and 6L80

Recently finished installing an L83 and 6L80 in my 63 Pontiac Catalina convertible. Used a Howell stand alone loom and they did a bench reprogramming on the ECM. The car runs acceptably but there are a few small gremlins that could probably be fixed with a final tweak and peak. It is beyond my capabilities and I am really not interested in purchasing all the equipment and learning how to do it. It should be a one time deal, my assumption is that once it is dialed in it will be good for the duration. It is my daily driver and will need to see me out as I do not have another build left in me.

I live near Thousand Oaks which is just slightly west of the Los Angeles city limit. Is there someone in the general area that is capable of doing a final tune on this combination, It would definitely be cheaper and easier to pay someone to do it than to get all the equipment and go through the learning curve and try to do it myself.
