My experience with them is on the Diesel side, but since a MK3 is Direct Injection, I think some things will work the same. Here's some of the stuff I know about:

It varies fuel/air ratios by modifying the controls to the injectors, it changes shift points on automatic transmissions for best performance, removes or changes limits that the Mfr. puts on things... that's just what comes to mind. Of course, if you have intake and exhaust mods, a programmer can take better advantage of them to increase performance. Also, a good tuner will have an "eco" mode where it improves MPG, sometimes very significantly (10 to 15 percent are not out of the question). On a car getting 39 mpg highway, that puts you in the mid 40s! Wouldn't that be nice on the next family trip to Orlando?

You can also get optimized tunes to squeeze the most out of higher octane gas like 91, 93 (and if you're lucky, 94...I'm looking at you, Chevron, why don't you love me?)

Around here, the 3 octane combo seems to be 87, 89, 93. I've never seen 94, is it Chevron who usually has it? I go mostly to Exxon/Mobil or Shell (or Sam's, which is Exxon around here, I've seen the distributor's truck there). But I'll try a Chevron for 94. Someone here got me on premium, best advice ever, my economy went up more than 10 percent from just that (or break-in, possibly, but I'll go with the gas).

When there's only 2 grades, it's 87 and 91 usually. I don't use anything but 93 so I skip those places. There's a station close by that has no-ethanol 93, but it's 40 cents more per gallon, and after 2 tanks, only about 1 mpg difference, so I am back to e-10 premium 93 at Sam's, for 40 cents less.

To go back to the topic, I'd love to have a tuner for this reason, as well. Of course, on the Diesel, there's no "grades" (there is No. 1 and No. 2, but No. 1 is just for cold climates in the winter to prevent jelling). Having a tune to tell the car what grade is in the tank instead of waiting for the "adaptive" process to happen would be GREAT.

I've 'heard' of 94 Chevron with Techron; I haven't seen it personally. It might functionally be about the same in-engine octane as Shell 93 V Power (the only fuel I put in my car).

I'd also appreciate being able to have an 'eco mode' map I can switch to if need be for long road trips when all out performance and stomping on it isn't a priority. It'd never make up the cost of getting a flasher just for that (before the naysayers speak up), but it'd be an excellent 'fringe benefit'.

Without a doubt if I were to get a tune it would be for premium.. I mean this car is 12:1 compression it should have already required premium from the factory but they detuned the crap out of the engine and retarded the timing to accommodate 87.

A tune on a stock car with 93 and advance timing properly done for a high compression motor like this should make another 15whp easy.

I would love the ability to go back and forth between eco and performance, like I do on my computer :P I got the Focus because it's fun to drive and gets me better MPG than my last car, and anything I can do to make it better would be great.

Not to mention anything I can do to make it closer to my friends G6 and cousins 06 Mustang when they drive near me would be appreciated :P

I'd buy a tune, if priced between 300 and 400 dollars. With the mods I've already done, my car would be close to 200 hp at the crank!
