What do you define lean? Lean is anything above 14.7:1, fuel delivery may have pushed the car's a/f nearer to this.
EGTs at 17.1 is less than that of 14.7:1 so simply correlating the temperatures to the fuel mixture is absolutely false.
The 950deg EGT was an indication that something was amiss and it turned out to be the fuel pump or fuel pump relay being faulty causing the motor to run dangerously lean.
