Rev limiter
Mine don't and its factory. Proof. http://www.youtube.com/watch?v=gfMqIaTMCw0
And I'll also confirm it's a 5200 RPM limit. The Mopar PCM removes the limit, but as previously mentioned, it floats the valves around 5600 RPMs. No reason to go past the factory limit with the stock intake manifold anyways.
