I recently installed the Cobb Stage 2 tune, and the check engine light came on throwing codes for the MAF sensor. How do I fix this?

So no Maf 07 Focus St?
No Mass Air Flow sensor on the Mk3 ST, 2013-2018, 2007 ST does have a Mass air Flow sensor. I have no idea how to trouble shoot your situation. Most members here have the Mk3 ST which is the only one released in the U.S.

We have 3 MAP sensors and no MAF sensors. So I would double check what that code is.

3 sensors, but only one is Manifold Absolute Pressure (on the intake manifold); the one on the intake tube is intake air temp sensor and the one on the cold side charge pipe is the charge air temp sensor.

Yep! Just saw the one post from 2 hours ago and started replying to everyone assuming they were one in the same. Silly me!
