Hi Sonny.....

Grab a coffee, browse through the many threads around here on all those topics you mention above.....not being harsh to you, but by reading the various threads on those topics you will probably find the answers to the next 5 questions that will arise as well :)

I personally don't get too hung up on LTFT values...heck, when my LS1 was dead stock it was all over the place, these days I force it into lean cruise as often as possible so my LTFT's are usually doing nothing.
They can be used as a good indicator as to the overall tune of the engine, but like many have discovered even a dead stock engine can have the LTFT's all over the place.....it's not the end of the world if they are.

Cheers,
Ross
