What should I be shifting at?
Just curious on a few things with my tune i'm working with Justin on. What should I be shifting at? I seem to be shifting early (6100-6200) and it doesn't quite pull up top like I think it should. idk maybe im hoping for too much with it.
Set up-
1999 RCSB 4x4
6.0 LQ9
11:1 CR
233/239 .595/.603 112
243 heads milled slightly, dual .650 springs w/trunion upgrade 7.4" pushrods
TBSS intake with 92mm DBC 4" CAI
LT and ORY into 18" Magnaflow with full 3" pipe back to the bumper(could this be a restriction? Maybe I should cut it off before the axle?)
Stealth 340 pump
44 lb injectors
BB Autocal Tune 93
Efans
4l80e with shift kit
Circle D 3600 Billet Multi Disk
3.73 gears with 275/45/20 (28.5") on stock 20s
Tru Trac
Video- kind of sucks with it spinning and shifting to 2nd, but what do you think?

I would be shifting a little later, around 65ish. Also when you do your runs leave the trans in 3rd so you don't get that down shift.. I honestly think that is to much cam for that heavy truck, the converter is just on the small side IMO..

Thats kind of what I was thinking, around 6500. I normally do have it in 3rd I must have not been paying attention.
I was afraid of that, I was trying to go as big as possible and still be able to daily it, hence the large end on the cam and small end on the converter.

Do you think I would see gains from a different cam? I also may swap back to 317 heads for lower compression and go FI next spring, im not sure yet lol.
