No one should discount the importance of proper gauges and diagnostic capabilities when driving an Ecoboost.
Proper gauges alerted me to a serious problem brewing in the Lincoln which led to the entire timing assembly, pcv, and water pump being replaced under warranty.
Very helpful as I was able to inform the tech of specific misbehavior. Made it very easy for him to reproduce...concern verified. Had I not been alerted, disaster was sure to ensue. I had planned to replace the water pump on my own dime but tech discovered shaft play so that was taken care of as well.
Lincoln is MUCH better to deal with than Ford on warranty issues. No push back whatsoever, they wanted the car handled and handled right. The Mrs tells me that is normal when she's dealing with Lincoln vs Ford. Definitely something to consider when deciding which to purchase.
