I and thinking about going to EFI Live but I am very satisfied with my current setup. Check my sig out. Is there a tune out there that will out run my stack?

A good EFI Live tune can be made to have a very smooth power band. Plus you can always change anything you want to with EFI. If your stack is smooth and you are happy with it, I'd say stick with it.

I have the same stack and I too wonder about EFI.
I can't say the my stack is perfectly smooth on the street but it is near enough for me. (throttle is little touchy at low speed).
