Redline and shift points

OK. I know this question is going to get a myriad of opinions but I was curious where everyone shifts and what the redline is. I think it's 5K RPMS but my motor sounds like it's going to blow up at 4K so I've never tried it. Is there a fuel cut off?

I have a tendency to drive mine like a sports car as well since I love the "power" it has. My understanding is that these motors don't like the hi-revs. I am sure plenty more will chime in....

Yeah I heard that too but I'm also sure that low revs aren't the best thing for a motor in the long run also. I gotta be honest, my brother revs his to 5k all the time and it's been no worse for wear than mine.

Normally around town I'll shift between 2k and 3k. Accelerating on to the highway I think the highest I've ever pushed it is 4k.

I think 6k is redline. stock tacs run up to 6k, though sometimes i feel like 4k is redline as the truck sounds like it will blow up!

Redline is ~5200-5250 ... err that is where the rev limiter is.

You guys need some engine mods. :P Get rid of the rev limiter. I'm at 5K every day. Used to run up into high 5's but bent some push rods. For about the last year I've been holding to 5K and no issues now. Tons of power at 5K, but I have a modded cam among other goodies.

Been trying to figure out why i lose all power at 4k. Seems Im not the only one experiencing this. Is it possible the rev limiter is set at 4k? How do you get rid of it?

between 2 and 3K is sweet spot. Higher sometimes to clean it out or HWY.

I agree that 2-3l feels like the sweet spot but my truck continues to pull up to 4k and then drops off like the fuel or spark is being cutting off. Its not acting like 4k is a redline where there is a gradual loss of power but more like there is some kind of rev limiter preventing it from going past 4k.

I seem to recall the owners manual stating that the usable power band was between 3 and 4K. I'm paraphrasing of course.

X3 2-3k is where it is at on the road with the occasional 4k on a trail to get over an obstacle but I feel guilty when I have to do that.
