I just got the Autotap with EFILive 6 Pro, and wanted to jump head first into tuning my car. I tried to read through the documentation and only understand about half of it. Is there any biginners guid or help files that can help out?

Main reason for my question is that I installed LT headers and Catback as well as LS6 Instake and new BBK TB, and find my MPG has dropped significantly, I can only think that the car is running rich. Any help would be apreciated.
