Alright got a 2004 6.0 with ls6 spring and cam! first to second at 6000 rpm is good(could to higher, still pulling) but second to third rpm feels too low! I feel like the thing is still pulling hard and it falls on its face going into third?
My question is what kinda rpm's should this set up pull to?

 

What is it at right now for 2>3?

My 216/220 5.3 is 6200 for 1>2 and 6000 for 2>3
Depending on your cam size You might take it a little higher, but with ls6 springs you probably shouldn't.

 

My 2-3 shift on my LQ9 just kills me. 3rd drops back down 3800 or so. Freaking sucks. What's your cam specs? I'd say cam permitting you should be shifting around 6400.

 

With that cam I'd say you should be shifting at around 6300 on the 1-2 and 6100 on the 2-3. A bit lower if you have more stall than stock.

 

1-2 for me is 6250-300, 2-3 is 6000, along with the 3-4

Why do you guys not shift the 2-3 as high as the 1-2?

 

I can't speak for everyone here but for me my 2-3 shift doesn't happen as fast as my 1-2 shift.
I set my 1-2 at 6400 rpms and it shifts out at 6400 rpms.
I set my 2-3 at 6100 and it won't actually shift out til about 6300 rpms or so.
If i set it at 6150 it won't shift out til about 6400rpms....at least this is how my rcsb works anyway.

 

stock stall with the 207( i think) 117.5 lsa z06 cam and yellow springs and i'm running on a mostly stock lq9 tune with a lq4 motor.
all my shift points are the same as they used to be with the5.3 just 5900 for first to second but 2>3 idk haven't logged to see just wondering what kinda rpm's i can turn without failure cause its still pulling hard before it shifts! feels like its got more there!

 

i turn my stock cam 5.3 to 6400 on the 1-2 and 6100 on the 2-3.
I would imagine even with the larger motor the cam size differance would be enough to turn your motor to 6200/6100 without any problems.

 

i shift my 6.0 w/a cam and tuned 6500 the way around it starts to fall off around 6700
