I was getting anywhere from 21-24mpg in my ecsb with a 5.3 that was just intake, exhaust and tune. Just because you have never gotten that doesn't mean it isn't true.

I agree with statements above, get a custom tune from someone who knows what they are doing. You will pay virtually the same amount and be much happier.
