I was thinking about bumping it up to 6000 just to make my 2nd gear last till 90 instead of 85. Because it needs all the help it can get from 85 to 100.

 

Hold it to the floor until it stops revving, then let us know.

 

turn mine 6100 all the time stock valve train no problems!!! knock on wood!!

 

see what your TUNER says

 

It also depends on what year model engine, I see you have an 04, thats what my brother has, an 04 extended cab z71.. I tuned his to shift at 6200 rpm. It's shift recovery into third is alot better. But me and my bro like revin stuff up! LOL... I would shift at least 6100... You wont regret it.

 

I'll definetly be asking Justin when I get it retuned, but I just wanted to see what everyone else is doing. Also to see if anyone blew anything up going to high.

 

was turning my stock cammed 5.3 to 6200

 

If you rev it past 5800 just keep an eye on the pushrods because then you risk bending them.

 

On the dyno with only bolt-ons and tune (no LT's), my power started dropping off after 5900.
