Tune, don’t tune, I think ford would fix your car either way if it were to actually break. I say this because clearly the two bolt is the engineered correct design. They know that. That’s why there’s the recall. They wouldn’t initiate a recall if these were only breaking on tuned vehicles. They would just chalk it up to the tune. So unfortunately that means it is happening on stock STs. So tune or no tune, the bad decision of the 3 bolt design can fail on stock cars. So how could anyone prove a tune did it. Plus, ford is in deep with this. I think they know the math and will take care of anyone with damage.
