who has a tune?
You could do that, I would think it'd be a lot more work tho. And you'd have to check to see just how lean it was running since you've got quite a bit of mods... I would think that you would need to add
Some fuel even to the stock map for the economy map. Detonation is not your friend lol

This is the part that confused me a bit as much of the tune is based on a margin of load values- whether you're in a power map or an Eco one like what seymore is saying if you trim down your low load sections for cruising and beef up your high load side for the spray and pray sessions... Don't you accomplish the same as having two separate maps? I guess having an Eco Map would help being low(Er) on fuel all the way through because then you wouldn't hammer on it at all which- if you're running tons of mods or FI- would gobble fuel.
So other than that is having a streamline, efficient power tune practical- or do you need to have more fuel dumped at all load levels in a power map to help keep things quenched for the upcoming high boost / high load condition?

Stock, dd, 100 octane, and valet. I don't understand how some guys have different maps for power and fuel economy. If you tuned for efficiency, you should have both, no?

actually, efficiency can be another type of map...jack of all trades, master of none.
None of the maps come with limiters or anything. When you start a tune everything is stock in the rom file, whoever is making the tune manually changes everything on each map. That means setting the rev limiter on each map.
Typically I recommend:
1) power
2) economy (same as power but leaner under 3000rpm and low load-- above that defaults to power
3) stock
4) valet or "GF mode" 4000rpm limit and 70mph
5) anti theft (will barely run)
There's no reason to NOT leave it in the tuned map all the time, the performance map is optimized for performance and efficiency and thus is where your car will run the best.
But back to the rev limiter bit, you can set the rev limiter to whatever you want on all 5 maps. If you're getting it tuned somewhere just specify how you want it set.

It's up to the tuner to set them, it's not a preset thing. You could specify which maps you want where when you get tuned
. Too lean damages things and can go boom, too rich just wastes gas
It doesn't really hurt anything when you're not under load, IE cruising on the freeway. There's a limit to how lean you want to go however, you can't just lean it out and get 45mpg... lol
Then I'd recommend picking up the tuner version of osiris and playing around with it and seeing just how comfortably lean you can get, a shop is going to tune very conservatively so if you're going for maximum fuel efficiency thats probably not going to cut it
