Seems a lot of talk about the gasser's "redline" needed to go up some steep grades. The 6.2's redline in 6000. Way above HP and torque. Absolutely no reason to go that high.
In another thread there is picture posted by a strong diesel proponent of his dash showing pulling a grade at 60mph. What the picture also shows MPG at about 4 AND 3000 rpms which is 500 rpms below his redline. So, a diesel roaring up a hill just below his redline is OK and isn't as loud as a gasser?
