not a bad idea but it all depends on what you are injecting.
to the extent it is methanol, post throttle body isn't the spot. methanol flashes/atomizes and as it does IATs significantly drop. 100% meth delivers a cold to the touch UIM. meth needs to be upstream a bit to flash. an easy and properly located spot for the nozzle(s) is in the silicone coupler immediately ahead of the Greddy elbow.
water could work somewhere post TB as it does its work in the combustion chamber.

That's how Bosch set up the OEM system on the M4 GTS.
See separate injectors on each intake runner. 100% water, 145 PSI system pressure, and injectors that are modified for longevity with water.
