Backfire normal?
i own 2017 CR7 Z51 3 LT automatic with 10,000 miles. recently while flooring it in sport mode at around 60mph there was a backfire. since then i have not been able to reproduce the backfire in ether track or touring mode. when i put it in sport mode i can get it to backfire again. Is this normal or something that needs to be looked at from the dealer?

Normal. It is a little bit of unburned gas which is ignited after the shift (assuming this is when you hear it.)
Note this is not a backfire. A back fire is when burning gas comes back out of the intake.
