The chat is stupid, and I don't know how people can keep track of it when it changes every 0.01 seconds. The 6.7 is looking like more of a beast faster than I thought it would. In a couple years the 6.7 will be the powerstroke to have.
Should be some nasty ones in a few years that's for sure. Hopefully the 6R140 will be able to hold the increased torque a little better than the 5R110 with the 6.4s.
