Rev limiter rpm is always a few hundred higher than shift rpm. Otherwise, the engine would hit fuel cutoff and kill the engine until rpm dropped. At least it was on my Dakota and Mustang when I tuned them.

All I know is my 12 SRT shifts at 6250.When I forgot to shift in sport mode, the rev limiter was bouncing off the red line at 6250.And that's all I know.

I've been driving with a custom tune for the last couple of years. The rev limiter is raised to 6650. I honestly forgot where the rev limiter is on our cars. I think you're right the redline is 6250 so is the rev limiter I guess.

It makes sense redline would be 300 rpm higher than power peak so when it shifts it falls back in the sweet spot. Wondering what rpm the A8 shifts at in D and where the rev limiter kicks in.

I am going racing the next couple of weekends. As I am getting more comfortable with the drag race, I am going to try to find those details myself. I will bring my Trinity and see if I can't use it for shift light and data logging on the 2015. I hope it doesn't rain this weekend, weather channel showed 30 percent chance, so, it sounds good!

Is it still pulling after 6250?On my Daytona I raised the limiter, it would go up there,but it quit making power,it was past it's peak.Then again with your custom tune they may have compensated for it?

Oh yeah it still pulls hard. No doubt about it. If you take the 5.7 for instance, I don't think it'll do it any good raising the rev limiter because the power drops after 5800 rpm I believe. If you look at the 392 dyno graph, the power curve stays flat all the way. It really helps me on the track. Sometimes that few hundred rpm comes in handy especially when your a short distance away from that turn and it gets you there without shifting.

My Shelby had a cool little feature. It was a shift light/tone that you could set for a specific RPM so you wouldn't have to look at the tach when storming down the road. I know that was a manual but it would still be cool to have on the Challenger. When I'm racing I like to keep both eyes on the road.

Have been reported. We do know that the original 392 was tested on a dyno limited to 465 HP. People who have been on this site a LONG time KNOW this. Based on this, we can safely assume that the original 470 HP number was an estimate by Dodge. The 15's may have more power...but we probably don't even know if 485 HP is a correct figure.

2011 392 - SAE certified - 467.1267 HP @ 6000rpm / 465.3667 TQ @ 4200rpm (470HP/470TQ rated output) - CTC test cell C06

2015 392 - SAE certified - 485 HP @ 6100rpm / 482 TQ @ 4100rpm (485HP/475TQ rated output) - CTC test cell C03

I believe the HP increase is due to the higher peak RPM (can also be achieved through tuning on pre 2015)/electric steering and the TQ gain is because of the 2015 straight through exhaust system/reduction of torque management in the tune.

My STi had that as well. You can program a shift light in the SRT model. Its in the SRT performance pages. I have a manual car so I'm not sure if there's one on the A8 cars.

Thanks for the info. I'll check it out. I still haven't explored all of the performance pages.

I'll have to check that out later. I'd go look but my wife took the car.

This is the big changer. In this video:
https://www.youtube.com/watch?v=ZwZt9FEh_lY
the Dodge engineer says the Hellcat was built to produce 850 HP and then detuned to 707 to provide high reliability. The "Torque Management Tables" really create the car performance you see in any new Challenger.

Are those ratings flywheel or wheel?

The 392 has had a 6400rpm redline since it was first introduced, the peak HP isn't happening at redline so it's making more power because it's making more power.
