6.7 Cummins; 5k Rev limit

[Garrett Moffitt]

Trying to play around with the rev range in my 6.7 Cummins, I am in the process of rebuilding the head as to not float valves. I am on this forum to hopefully learn how to turn up my engine timing properly, I understand this is not healthy for the engine but that is my choice and I am planning on rebuilding the bottom end before it runs. Any productive response would be much appreciated. Thank you.

I would speak with a good tuner and tell them what you're after as a lot of it is in tuning with the newer trucks. I would recommend CTT tuning or Firepunk
