About this app

Built by CJR Performance, the Mopar tuning and dyno shop in Pickering, Ontario, this app keeps your car's whole story in one place: what's been done to it, what it ran, and how it stacks up.

Made for Mopar owners: Hellcat, Demon, Challenger, Charger, Ram, Durango, Trackhawk and more.

TIME SLIPS
• Keep every drag-strip time slip in one place, with the track and date.
• Reaction time, 60 ft, 1/8 mile and 1/4 mile ET and MPH, whatever is on your slip.
• When weather is recorded, see ET and MPH corrected for density altitude (SAE J607), so hot-day and cool-day runs compare fairly.
• Tracks include Toronto Motorsports Park, Napierville, St. Thomas, Grand Bend, Mission and more.
• Paper slip? CJR snaps a photo, the app reads the numbers, and we check them before they're saved.

BUILD HISTORY
• A dated timeline of the work on your car: tuning, fuel, superchargers, turbos, wheels and tires, maintenance and more.
• Always know exactly what's on the car.

LEADERBOARDS
• See how public builds stack up by track: best ET and top MPH.
• Sort by weather-corrected ET for a fair comparison.
• Your car stays private unless you choose to show it.

MORE
• Comparable builds: see what similar CJR builds ran before your next mod.
• Upcoming CJR events, with optional reminders.

PRIVATE BY DESIGN
• Client accounts are invite-only. CJR Performance sets up your account and sends you a personal sign-in link.
• You only see your own vehicles, build history and time slips.
• No ads, and we never sell your information.
• Privacy policy: https://app.cjrperformance.com/privacy
