You aren't getting the enhanced engine. So i don't know why you put up a link to it?
The original F414 was a 7 stage engine, the new ones are all 6 stage with new cores. Hence the "6" in INS6.
Indian programs don't need the Enhanced Engine, 'cause all the jets involved are lighter than the SH.
At this stage, it is the INS6 you are getting and the power specs are the same 22,000lb for the 400, As i showed and someone else said.
