You may want to print out the break-in procedure and tape it to the dash, just in case.
I didn’t know that there’s a break-in procedure for this car. What is it?

Sorry, I don't know what it is for your model Challenger.
You can download the manual, which probably doesn't have much info about the procedure, or Google it.

I printed it out for my '18, and it turned out to be the same procedure for the '19 even though the '19 has more power.
In my case it's a 500-mile, three segment, list of allowable speeds and engine rpm.

It may also be worth to use standard diff gear break-in procedures for the first 100 miles, or so, getting the gear teeth properly work hardened.

you can download the owner's manual from the dodge website.

Its also pre-loaded on the uConnect radio from 2016 onwards

the 392 equipped models have a multi-tier break in

mentions both max engine rpm and mph recommendations (for differential break in as well)

launch control isn't enabled until 500mi cumulative use is reached

the 5.7 engines have a less stringent break in recommendation

For vehicles equipped with the 3.6L or 5.7L use the following engine break-in recommendations:
A long break-in period is not required for the drivetrain (engine, transmission, clutch, and rear axle) in your new vehicle. Drive moderately during the first 300 mi (500 km). After the initial 60 mi (100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable.

While cruising, brief full-throttle acceleration within the limits of local traffic laws contributes to a good break-in. However,wide-open throttle acceleration in low gear can be detrimental and should be avoided.

For vehicles equipped with the 6.4L use the following engine break-in recommendations:
Despite modern technology and World Class manufacturing methods,the moving parts of the vehicle must still wear in with each other. This wearing in occurs mainly during the first 500miles (805km) and continues through the first oil change interval.

It is recommended for the operator to observe the following driving behaviors during the new vehicle break-in period:
0 to 100 miles (0 to 161 km): • Do not allow the engine to operate at idle for an extended period of time. • Push the accelerator pedal slowly and not more than halfway to avoid rapid acceleration. • Avoid aggressive braking. • Drive with the engine speed less than 3,500 RPM. • Maintain vehicle speed below 55 mph (88 km/h) and observe local speed limits.

100 to 300 miles (161 to 483 km): • Push the accelerator pedal slowly and not more than halfway to avoid rapid acceleration in lower gears (1st to 3rd gears).

• Avoid aggressive braking. • Drive with the engine speed less than 5,000 RPM. • Maintain vehicle speed below 70 mph (112 km/h) and observe local speed limits.

300 to 500 miles (483 to 805 km):
• Exercise the full engine rpm range, shifting manually (paddles or gear shift) at higher rpms when possible. • Do not perform sustained operation with the accelerator pedal at wide open throttle. • Maintain vehicle speed below 85 mph (136 km/h) and observe local speed limits.

For the first 1500 mi (2414 km):
• Do not participate in track events, sport driving schools, or similar activities during the first 1500 mi (2414 km).

That part always cracks me up. How would you stay under 85 mph with sustained wide open throttle?
Under 185 mph, maybe, if it's uphill.

2nd gear? You'd get high rpm, but the gearing is so low that you'd reach redline before getting above that speed.

Anyway the wording is to not run sustained WOT. The part of staying below 85mph is during the 301 - 500mi of accumulated use.

The diff break-in is the main part of the speed limits to allow heat cycles w/o excessive wear on the new assembly

Yeah, you could sit there in Second and bounce off the rev limiter for a few minutes, I suppose.

Either way, I don't even know where one could run WOT for sustained periods, other than on the Autobahn.

Diff break-in seems to be a forgotten art. I'm anal about it, and still have my fair share of issues. Thankfully not on a Challenger, yet.
