DFI7 or FAST?
Look into the BigStuff3 system, it can control an electronic tranny unlike the FAST of GenVII. With either system you would get rid of the Mass air sensor, and run a MAP sensor. Call White Racing about a harness, I know they make a harness adapter for my truck, not sure about the newer stuff.

The BSIII sounds nice also and is plug and play for LS1s also I believe, it would be cool to have some kind of demo software for it..
Its an expensive decision, the Gen7 was in the car when I bought it so I didnt have to make that choice
