Message	On the dyno, my EGTs never go above about 780-800 C. But on the street, EGTs right now, at the same boost level, are in the neighborhood of 820-840 C. However, I can have EXTREMELY high EGTs with perfect air/fuel if my timing is retarded too far. So the 2 don't necessarily go hand in hand. I've found too that advancing my timing results in lower EGTs. These results are from my 89 Pontiac Sunbird running 15 psi of boost. 76 280Z 89 Sunbird GT Turbo 9.7@73 mph 1/8th mile 02 Accent GS
