With my 4.88's I hit the rev limiter at 83 mph in 6th gear.
Does this sound right?

This is in gear though. I don't ever remember the RPM's getting that high even at WOT about a month ago. I was seeing like 2800-2900 at the most.
I am perplexed. Something has changed, and I just washed my hands and tools.

I have a six speed and can bring the R's up to 3300, I think. When I replaced a couple of injectors part of the process is running it that high for 10 miles to work the air out of the high pressure oil rails.

I saw 3500 on "stock" settings, and the truck isn't pulling like it used to. I seem to have lost my medium and upper power. I will probably end up removing the transmission and torque converter to investigate.

You are right Cookie, I can peg my 6S in any gear but OD. Just seems to run out of ooomph! Looks like 2900 RPM and 96MPH is the limit.
