Got my dragy 4 days ago- just took it out of the box and charged it up and loaded the app to my phone- tested it on my stock 2020 f-150 super crew 4x4 with 35's on it- mildly impressed went 14.73 at 96.12. device is kinda neat and well worth the 150 dollars- looking forward to using it on the mustang this week. every car person that is into performance should own one.
