2016 Focus SE Tune Compatibility

[Griffin.Evans14]

Hi, I was wondering if I could use a Focus ST tune on my Focus SE. I really want to put a Mountune tune on my car but they only make them for the ST and the RS, and I would like to know prior to buying one so I don't screw up my car. Or have it just straight up not work and being out a bunch of cash. Thanks!

You can't, since the fuel, air fuel mix is completely differently. Not to mention you'll probably end up ruining you car.

Why not just get a tune for the MK3 Focus? https://focus-power.com/product-category/ford-focus-2012-2017-duratec-ti-vct/
