Default longterm fuel trim

I'm new to this tuning stuff. Just wondering is a -1.56 on both banks ideal for my setup. Mods in sig....

yes...

if at steady cruise on the highway with rpms around 1800, if your average ltft's are between 0 to -2.xxx, that is good!

Yeah thats damn good, you don't want positives. Or too negative 0 to -5 is what your shooting for but -1.2 is really good.
