12, but I still have other kr issues which I might add, I believe is in direct correlation to the compression ratio. I will get kr if I snap the throttle and let off...0% to 80 or 100% for just a "blip"...but if I floor it from a stand still...no kr. I have lots of kr in the low speed/heavy load area. I do have a WB o2 but haven't finished hooking up to see how my timing and ve are doing at WOT with afr in consideration. That 12 degrees is with race or pump gas.
nevertheless...12 with no kr. I'll see kr at 14 for sure. My compression is an estimated 10.2ish maybe just maybe a 10.5...5.3 heads(shaved .010) on the 6.0L
oh yeh...8psi of boost

i've managed to program them to run over 20º on SS trucks when the IAT is under 100 with no KR*. i have the logs to prove it. one of the trucks has a 2.8 pulley also. by the end of a run the IAT's will creap to around 150 or so and i have it pulling the timing to down around 15-17 if i recall.

in order to have alot of timing like that you need to run a really well worked over IAT table. one thing i've noticed in tuning a radix truck is that if you have one with a small pulley on it the downshift you'll always get some kr*. if you program it out you'll lose some on your driving in the time that you're in the same range, but not under the same load. a radix with a small pulley will actuall make up to 5psi of boost before the trans makes the downshift.
