Sounds cool to me. Not sure why there's all the hate. Can't we all just get along, and nobody buys a mustang worrying about gas mileage. If you do, you got the wrong ride, go get a Nissan Leaf.
I figured the PC was on order or still sitting in the box which is why the ghost cam tune was working, but I heard the blower right when you started the car in the second video. Also you had the car at a much better temp to really hear the lope.
Lund told me the exact same thing about not having a good centri tune or chasing issues when he sent my ghost cam file and mine wouldn’t even idle steadily (idle surged, almost stalled then high idle and repeat) so I flashed my normal tune and never even used it. Maybe your ‘18 works better with di or since it’s a manual.
