So just a little about my setup 92 GVR4 with FP big 16G ported and clipped, 710cc injectors, 255 lph pump, jackal speed density setup, stock cams stock bottom end. So i just installed my zietronix EGT probe and saw EGT's of almost 1200 under light load. I have tuned the volumetric efficiency and just kept n eye on my AFR's so the ignition timing is a basically a stock map. Cruising me EGT is around 600 to 800 degrees. I have no idea what a dangerous EGT is. Should I mess with my ignition timing and try to cool it down? maybe the timing is to retarded for this better breathing setup? And also what should my target air fuel ration be at 15psi of boost with this turbo and stock internals
