Yea, it sounds like you've got a reasonable setup now. I have the 6530 box and it may give you a few more options than you have now. It has programmable launch rev limits/retards, burnout rev limits, and a fully programmable timing curve that you setup on a laptop. It's more of an all-in-one box. You'll need to buy a separate map sensor for it, but a gm one is cheap. You can set it to match different types of map sensors so you don't have to get a certain one. I like how you can even tune in a start retard at the beginning of your curve if your starter has trouble cranking your engine.
