Doesnt have to be. It's all in how the tuner writes the tune. Now I know how you Chevy homos like your lope tunes but please dont be that person.... :flipoff1:

Haley, what kind of mileage you getting? Does it get rid of def?
Mine is stock and got around 11.5 towing fifth wheel to the beach. Running 70mph.

I no longer have either due to blown heads and a wreck on the other.
Real world numbers if driven 70 on interstate with cruise I could do around 20-21. Towing I was around 10-12 mo matter how I drove it.
It is hand written tunes and if you only want one tune they can do you just an economy tune instead of the 5 tunes most go with on efi live.
I always dealt with Idaho Rob but there are several that can do efi live like you want.
