I hope your engine didn't get hurt too badly. That is a classic way that engines are blown. You had high intake air temps, spark timing off, cam timing off, fueling off (but maybe rich). Best case scenario spark was very retarded and fueling was rich and you are ok.

Good luck.
it was retarded at the max and the fuel was so rich. i was maxing out my wideband once i did a pull.

thanks for all the people that helped.
will have numbers up once i go back to finish my dyno tune.

I have the ceramic coating, and my **** glows a medium red at night. I run more spark advance in boost than anyone here. Cast iron glows at 1100*...if its not that hot, then something is wrong. SS glows even lower.
