My question is what gas are you running?
If 93 how are you running 12 pounds safely and making good power? My understanding is you'd need to retard the timing significantly at that boost, really hurting power output? The stock LS3 compression of 10.7 (or is it 10.9) is pretty high for 12 pounds on anything but E85 or meth injection as far as I can understand.
