Default TJT 3000 thrust?

After the misleading thrust claims by Simjet (my "3000" puts out 25lb @ sea level @ 76 deg F.) I want to be sure I'm getting the motor performance I am paying for.

The TJT website (Performance specs ) shows 12.5Kg/33.6lb (wait,12.5KG = 33.6lb????) thrust rating ,but RCJI and others refer to this motor as a 27lb class motor.

What is the actual thrust I would measure TJT3000 at sea level and say,80F?

This is for a BV F-4 and I don't want to be flying at higher throttle settings if possible.
