JK won't rev past 4,000 rpm

Tonight I put my JK in neutral as I was rolling through my neighborhood and revved my engine because my son asked me to. It wouldn't rev past 4,000 rpms with the pedal floored. Since the red line is at 5,500, I assume this isn't right.

This seems bad. Is it bad?

It has a neutral revlimiter to protect the engine from people like you

No, it's the computer protecting your engine.

Toss it in a low gear on the highway if you want to grenade it. We 6spd people can still over-rev if we want to!

The trick is not to post it on a public forum so you won't be known as the "stupid one"!

To the OP, sometimes you don't HAVE to do everything your kids tell you...
