FiTech Ultimate LS with Trans Control - Anyone using this?

[Barrrf]

Currently Im having a bish of a time getting my assembly to run correctly. Its a Gen 3 DBC computer tuned with HP Tuners with the help of Vengeance Racing. Im getting some idle surge and idle hang that I cant seem to get tuned out. And Im getting no help from Vengeance on it.

Aside from that, the overall size of the Gen 3 computer is ridiculous. So Ive been thinking about picking up the FiTech unit with the touch screen.

Looking to see if anyone has used it and if it works as good as they say it does.
