twin turbo pilot

i was reading the strategy on my xcal tune and it read FBFG2TY im assuming this is a code for what the people who tuned my car did. Any way to know exactly what that means? They wouldnt tell me nor did they give me a dyno sheet, the only improvement i saw was they set the speedo for 4.10s and i now have to run 93 octane. Oh yea my CEL came on as well im assuming they did not turn off the rear o2s and i cant figure out how to do it. Anwway needless to say i wont be dealing with these people again. They seemed really reputible and have some wicked cars. But everytime i asked a question they seemed annoyed or they said we really only deal with 03/04 cobras. Irreguardless whats done is done any help would be appreciated.
