It should richen it slightly but how much that would depend on the injector and pressure size, ive never noticed any vast changes in AFR even with an M5

The water evaporates so all thats left is the methanol which ups the octane, higher octane less chance of knock, lower EGT, you can run more timing

This answer would depend on the setup and theres too many variables
