An aftermarket tune can be removed but what guarantee does the owner that all traces of it gone? Making assumptions can be both careless and expensive.
Thats a side conversation you should have again at your servicing Ford dealer. They get paid on warranty claims. Then YOU again will know your options. Some dealers allow more flexibility let’s say. This is not that complicated folks...
Agreed, but things change. Dealerships change hands, service managers change. What your told today could change tomorrow. I would add that you get things in writing. A verbal agreement is not a contract.
Yes, there is a counter that increments every time you change the tune. They won’t know what the tune was, but they _will_ know that you’ve been messing with it.
When I had my intake manifold replaced under warranty, the first question they asked is what modifications I had done to the car.
I had a random misfire, most pronounced at low engine speed. If you were cruising your feel the car surging. Intermittent CEL. P0300 and some other codes.
