    Hey Focus Freaks, I drive a 2017 ST with a stock down pipe, ford performance cat-back, and a Turbosmart Bov. I recently sold my Cobb AP due to no support for tunes running flex fuel and ended up switching back to my Ford Performance tune. I got bored of rarely getting to hear pops and bangs...

    I don’t why but on my ap it says that the focus st only makes 190 hp and when on stock it says 270 is this a problem? Stratified tune might have an issue but it feels decent nothing really noticeable

    I have been running my Stratified tune for a couple months now, and I absolutely love it. The only problem is I can’t figure out how to have the traction control stay on. Evert time my AP turns off the traction control goes back to off. Any idea how I can change this?

    Hey Guys, Yesterday I made a post which i discussed me throwing a code for my upstream o2 which may be bad, so today i tried to go about it myself and fix it. I made my way all the way through til i got to the o2 sensor and was unable to twist it off to remove it. So i decided to put everything...

    I have been doing a lot of research into possible modifications for my FOST. I have saved up enough money for an accessport and am thinking of going for a stratified tune. I only have a MBRP catback exaust, air filter, and bov. Should I do any modifications prior to getting a customized tune? Do...
