i have the U7140. It works. the software works for both V6 and V8. Trust me dude, you should have no worries. This is just an error on Diablo's part that they didnt update the correct info/literature in their tuner manuals where it SHOULD say that it works with 4.0's also. I've spoken with Diablo on the phone several times. They have been pretty helpful every time i've talked to them. good luck.
