The car seems to run ok, but only gets around 22mpg in mixed driving. It has the PZEV 'emissions' tune, which probably has a LOT to do with it.
I would LOVE to have a better tune for it, as I believe it would significantly help both fuel mileage and power.
Does anybody offer a decent tune for these cars?
Mine is still stock, and has an auto trans.
Does Tom offer a tune for these cars?
My 'other' car is a 1966 mustang street/strip car that I've had since age 15 (I'm now 43) that I've played with and massaged into a 10.15 @ 134mph toy... and have built all the engines, transmissions, rears, and done all the mechanical work on.... so I'm very familiar with mechanics, but not 100% up on Focus ECU's. LOL!
Thanks for any help!

Hello, Yes I do Custom Tuning for your Focus , I charge 399.00 and 20.00 for shipping and that comes with free updates as you add more NA mods
I am also playing with a MPG tune that will also be free

Do/Did you take this into account for the PZEV's?
Changes to the engine management software along with new low-rolling resistance tires nets a 3-mpg increase in highway mileage for the 2007 Ford Focus 2.0-liter with a manual transmission.
Ford Motor Company’s razor-sharp focus on the consumer has prompted the company to make some dramatic improvements to the 2007 Ford Focus.
Powertrain engineers concentrated on the 2.0-liter inline four-cylinder, improving fuel mileage across the board.
“The Focus engine was originally calibrated for emissions,” says Nicholas Schubeck, supervisor, Powertrain Calibration for Ford Motor Company. “We noticed during testing that we could get a lot better fuel mileage by making some adjustments to the calibration while still meeting emissions.”
The team increased the engine’s spark and revised the exhaust-gas recirculation and intake manifold runner control (IMRC) schedules. The IMRC is a device on the intake manifold that increases the velocity of the air going into the cylinder at low speeds. Increasing air velocity helps in the proper air-fuel ratios.
“The issue is that the system also creates a lot of pumping losses, which reduce fuel mileage,” says Schubeck. “By opening up the IMRC a lot earlier to reduce pumping losses, fuel mileage was increased.”
This change, along with tire improvements, accounted for a 3-mile-per-gallon improvement on the EPA highway fuel economy label for five-speed manual models, which now see 27 mpg in the city, 37 mpg on the highway. The 2.0-liter automatic delivers 27 mpg in the city, 34 mpg on the highway. For 2007, the base Focus models come equipped with 14-inch Hankook tires that offer better rolling resistance than the 2006 model.
Schubeck says customers will also notice an enhancement in performance. The extra engine spark improves acceleration, and the refinements to the engine have eliminated the hesitation that normally occurs when the air conditioning is is in operation.
