Exactly as Gary syas, if V2 drops significantly, you have winshear and a recovery process to initiate.
Remeber however, you may fly V2 to V2 plus a speed factor additive if you are already there, to a maximum of fifteen knots in a OEI scenario. If you have a windshear event OEI, then you are having a bad day, but you still have to fly the airplane and do the best you can.
As far as V1 goes, this is a ground distance issue for rejected takeoffs and continued takoffs with OEI. No gust factor, no additive, nothing like this at all! If V1 is adjusted it must be done only per procedure, not on a whim, or it could add unscheduled, spectacular light and smoke shows to the nearby airport residents.
