I have a 2004 1500hd lq4 with 100 shot of nitrous I sled pull with wanted someone to take a look at the log and tune i have see why its pulling timing? Maybe just knocking and I need to run less timing? I only run this tune when sled pulling. motor is bone stock runs on 93 and has a wet shot hooked to the fuel rail

What's your wideband showing for fueling??
Just because you are commanding 11.94 afr, doesn't mean it's actually there.
Your also revving the engine pretty damn high if you have a stock camshaft and valve springs. If that stuff is stock you are way past where you should be.
Back the timing off to 20-22 degrees and probably zero out the base spark adder for the gas table. That is adding to your current commanded timing and isn't helping if it's already knocking.
yes the motor is bone stock. The afr are in the high 11's on the nitrous
