I got 26 outta my truck dead nuts stock on the highway. And the 4.3 isnt exactly efficient. So I'd believe a well tuned 5.3 could match it if not a bit better.

Denton Texas, they're right down the street from me, maybe two miles away and the first mile is just getting out of my housing addition.

Youll spend more money on a handheld programer and get less results. None of those are worth the money. Contact nelson performance and get a real tune. Hand held tuners are JUNK! No matter what brand they are all junk. The only way Id reccomend using a hand held tuner is like stated before having nelson send you one with a custom tune on it other wise dont waste your money on any hand held tuner!!!
lol 27mpg...
i dont think i have even heard of any V8's getting over 22mpg... not even the new hybrid trucks... i want a tune where i can get over 25mpg and still smoke people haha
When I drove my buddies cammed/stalled 6.0 rcsb I got 25-28
1983 Ford Ranger- 2.3 to 205k mile 6.0 swap
I would have to see that to belive that.... exspecially with a stall and a cam...
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.
