Is there any tuners out there that will raise the rev limiter on the LLY. I have the edge right now but will gladly take it off for a tuner that has that capablity

Check out the Predator. It will check your diagnostics as well as raise your speed limiter. It is a programmer.

Well, I believe that the predator can ditch your top speed limiter... don't know if it can raise the redline though.

I was just curious cause my buddy's 6.0 revs out to 4000 rpms and the max can do around 3100(with my experience).

The tuner I had on my older dodge raised the red line 1000 rpms and I was jw if that was possible on the Max

Yes, it's possible to go higher. Look up rev limmit or TTS. The Ford....I think it's 3,800 right out of the box.
