contreasjun27: u want lower FC, sure can, tune ur engine leaner but it's dangerous...

I tried tuning low RPM leaner, vacuum reading totally out. Suppose to be 18 psi - 22 psi of vacuum, the leaner i go, lesser the vacuum and exhaust starts fire cracking...

As lean as you go, it would have a certain limit, a sudden rise of fuel consumption might caused by other factors. The most obvious one is your own driving style, ignitions, exhaust leakage and many more...
