Exactly this. I unexpectedly got the recall when they replaced my steering box and there is 0 change to the performance of the motor and I regularly take it up to the rev limiter.Again, there is no engine detune. It has exactly the same power, feel,, and performance as before the flash. It's just a safety feature that only kicks in under extreme conditions.
This has to be the most misunderstood recall I've seen, and I blame Jeep for not properly explaining it. But the engine has full power unless there is an excessive amount of slipping detected. Enough to cause an overheated clutch. Only abuse or a problem would cause it to go into what should have been described as a limp-home mode.
I have not yet seen one person on the forum experience it. Even I didn't experience it when teaching 3 of my kids to drive a stick. The only thing I experienced even then was heartburn.
