Exactly. The logic doesn’t work in Ford’s favor. We also give up hp and tq for a “safer” tune but we have the mother ship’s endorsement.Another data point, service manager today actually recommended it... I said well doesn't that void my ESP... he said as long as it's installed by a authorized Ford tech there is no impact to your warranty....
I mostly agree, and I think it would be WILD for Ford to sell a product with their name and blessing, then say it also caused damage they won't cover under the vehicles ESP... and the letter of the law says they must PROVE a modification caused the damage...
Willing to bet if you showed them a please come to court paper they'd back off, but the service manager really gave the impression this just ain't gonna happen. He has the tune on hisown Bronco.
Iva head tune for 5k miles and zero complaints. All positive.
