Gentlemen...
In the 737-700 I'm familiar with, the first push of the TOGA button...
"advances thrust toward the reduced
go-around N1 to produce 1000 to 2000 fpm rate of climb."
...not as mentioned earlier, a specific thrust setting.
You will get whatever thrust is required to get and maintain 1000 to 2000 fpm rate of climb.
Cheers...
