Pulley change would not void because if engine got hurt, you could swap it back and ford wouldn’t know because the computer wouldn’t show the battery was disconnected
Does it drive fine? I mean stock ecu tune should be able to compensate for it. It won’t make the best power. But it’ll do fine. I had my 2014 gt500 drop the tune and I drove around without knowing for a week.
@Snoopy49 dealer told me 11/15 to the day. I’m hoping it changes sooner as it is a Ford Perf Blue car and some of those are getting built sooner. My vin is 1034. Please keep an eye out lol ugh so freaking close
