I know this is beating a dead horse. I have been researching the Diablo tuner, both the Predator and Trinity. I was leaning more towards the Trinity, however, a friend of mine suggested the EFILive. I have read information on the EFILive and found that it does pretty much the same thing and has the autocal. Which would one recommend, the Trinity or the EFILive. Now with the InTune which would be the best way to go, the Predator, InTune, or the Trinity. I like the fact that that you can leave the Trinity plugged in and see what is going on.
