You might want to list your tune vendor so you can get feedback from others with the same tune. I have Livernois and no symptoms as you described. Only thing was that the transmission had to relearn after flash.
Yup, worried about the mpg with the Livernois tune but in the end the spg easily made up for it but for what it's worth my mpg is slowly creeping up with a even more spirited driving then prior to the tune.
Sigh...I wanted that 2.7 for the Ranger. Nice ute.
Edit: Just googled the pricing on the trims. It's not cheap.

I was in the same boat as you with the same reasons but I did some research on high mileage ecoboost engines for the F150 and Mustang and found out that they are very reliable engines. FP also released their own tune which makes me think the tune is not really stressing engine and is engineered...
