|greg hazlett||The only way to make more power is to add timing until the engine stops making power and to lean out the a/f....until someone can tap into the Ford fuel trim maps, write programs to adjust them and then make them available to the public...well.....might be a while....companies are not going to invest that much money into the R&D unless they feel the market would support it and I am not sure the average Focus owner would be willing to pay for the tune, pay for the tuning device, pay the additional money for 93 octane and then not bitch about ther reduced MPG.|

|Sonic_HedgeHog||People are already seeing close to 20hp gains with intake and exhaust without a tune... So... I'd hope there is more to be had with a tune.|

|lookin4trouble||A custom tune with I/H/E should net you much more than 10 HP, but the handheld tuners are mostly made for intake only and indeed won't give you that much extra power. You can get a lot of extra NA power out of a 2.0L 4 with more aggressive cams, long-runner IM, long-tube cat-less header and a custom dyno tune. Whether or not anyone will ever make any of that for this engine remains to be seen. FWIW - Honda's K20 can push 260+ WHP NA.|

|greg hazlett||Exhaust is not going to change the a/f and the intake systems are designed to be non tune required; the cars might benefit with a dyno tune but at the most I would say they would gain is 10 hp and that it not worth the price of the handheld tuner/dyno time/price of 93 octane.|

I think people want this too if they are doing intake/exhaust mods in order to tune the fuel/air ratio. Right? Can SCT tuners do that for other cars?

|VH5150||I have an SCT X-Cal2 with 3 custom tunes for my Ranger--it made a big improvement with the 4.0/auto combo. Your greatest gains are always going to be with the higher octain tunes. The biggest advantage is being able to mess around with the trans settings. Hopefully, when (not if) SCT comes out with a tuner for the Mk3's, it will have some of the same options for the trans and engine tuning. The real key for any programmer is having somebody develop and load some "custom" tunes, not just the stock tunes.|

On a NA car the only thing that can be done is to mess with the timing, you can add timing until the car stops making power but this also means using 93 octane fuel.
There is only so much power to be had from a 4 cyl 2.0L engine.

Anybody have any proven results thwese do anything. In my past experiences on NA cars I've seen next to nothing and on turbo cars they can raise boost pressure and change the fuel map a little but it can be done better and much more efficiently through a boost controller and a remap of the ECU.
You probably get a little perceived umph from better throttle response but you can't make more horses without both air and fuel and I don't see how a chip can do that.
