You have to understand something about EFILive....it is primarily a scanning and diagnostic tool to allow you to use your computer like a Tech2. The side benefit that came out of it was that you could change engine parameters, and therefore "write" new tunes for your engine. This then became the BIG selling point for EFI with the racing crowd...how cool is it that you can change your tunes easily at the track, or even change one item? IMO, if you take the time and learn how to tune, you can see more (and larger) power gains using EFI than by using a regular tuner.
But, to get good at EFI tuning, you have to experiment with a LOT of different tables in the engine programming to write a tune. This takes a while, and takes lots of logging, and in some cases, lots of dyno time. Thats the reason I did not go with it myself. Maybe in the future.
Look at McRat....Pat had to experiment with a lot of different tunes to find what would work and what wouldn't. Look at Bobo....he's put in 100's of hours of work on his truck, writing tunes.
EFI is really not for the "average" guy looking for a quick program to load into his truck for more power. To do that, you'd need to buy a program from someone else, and use your EFI cable to load it into your ECM. I would highly recommend EFILive to anyone who wants to put the work into writing his own tunes. It is overall one of the best tools out there.
