1400F? 1500F is perfectly fine and normal for EGT temps on the highway. Unless the probe is in your downpipe or something, 1400 is fine, and actually a bit on the cool side. (Which is ok, though your gas mileage will suffer). Do you have a datalogger of some sort to help tune? Also how far is the probe from the engine block?
