Need Advice on performance upgrades on my 2015 ford fiesta.

I am wanting to spice up my ford fiesta 1.6 litre 4 cylinder hatchback. I am starting with a K&N cold air intake. I am wanting to get an ecu performance chip. Would like suggestions on the best ecu chips for my car as well as other performance upgrades I can do. I'm looking for a quick car on take off and for the short stretch. Also would like to make it sound tougher but not too aggressive.

Unfortunately, no chips, reflashes or piggyback ecu's have ever been offered for the non-turbo 1.6 L Fiesta.
If anything had been done, we would be able to do hotter cams, bigger throttle bodies and higher flow fuel injectors. As it is, the PCM is locked and the involved upgrades are being done on the ST version.

I have found performance chips from diablo and sct that state they work in 2015 ford fiesta 1.6 liter.

Pick one and report back on it! You and I are not the only people who are interested. I have stopped searching for any kind of reflashes or chip since 2014.
