The V speeds for a FLEX thrust takeoff are also valid at TOGA (FCOM-PER-TOF IIRC).
If you increase thrust to TOGA you will accelerate faster and reach V1 in a shorter distance (all other factors being equal).

Reading literature from the manual does give a little bit more information but if at the start of the takeoff roll you decide to use TOGA instead of say Flex 40, what increase could I expect in terms of distance or a percentage increase in thrust?
I hope this makes sense.
