Before you go any further get your coolant temps under control, that should be the #1 priority right now. The ECU is already pulling 2 degrees of timing to protect itself from the abnormally high coolant temps, not too mention all the knock thats going on as well. Activate Fans Full on under the Misc tab and go from there. Look into getting a lower temp thermostat or removing it all together if you have a good stock/aftermarket fan setup. If you keep doing WOT pulls with the way the car is tuned right now the head gasket will eventually give-way. The Check engine light should of been on the second you went WOT, from the knock value set on the Dash controls, this is basically very similar to the Idiot light for the oil pump letting you know oil is very low. When the dash light is on make it your duty to find out why its on, and FIX THE PROBLEM before you cause more damage.
