The dyno numbers never have been right for you imo, either the dyno or operator is off. I think the stock cam makes power up to that point to give you an idea..
Also there's something to be said about helping shift recovery when going higher shift points as well..

Since you run shifts at 6200rpm now try another 100rpm and test that and maybe go from there up to 6400.
You gotta remember this is a forum and like any other forum you need to take everyones post with a grain of salt. Just because people say they run a certain shift doesn't mean you should. Get it dyno tuned so you know everything is right. I just don't wanna see you try and compare to someone elses similar cam that supposedly runs for example 6700rpm shifts, then you go try it and mess your stuff up. Yeah these engines can take abuse but I would stick with a shift that YOU feel safe at.
You just gotta be careful what you read on forums sometimes. One example I see a lot on forums is a lot of guys on many forums says cam swaps on our trucks take 4 hours which is not true lol.. Maybe someone that works on LS engines every day for a living can do it in 6 hours that has the proper tools etc can do it fast but someone that is not familiar with these LS engines may take 3-4 days and you need to make sure you have all the right tools on hand.
Maybe you understand what I'm getting at different people have different experience levels. I just thought this all needed to be said.

Feels good all the way. I wouldn't go pass 6500 thou, I know shifting @ 5400 sucks, 6000 not to bad, 6500 it's a monster. I really thought it was my exhaust holding me back, but my last dyno was with cutouts open. With no change in power curve.
