...if running just Water injection how many degree's would my charge temp drop?( i know each engine is differnt but what a Rule of thumb figure?

It mainly depends on what the charge temperature is.
If your intercooling is effective and that temp is usually below 30C then don't expect much temp drop from the W.I.
If your charge temps are very high (say you have no intercooler) then the W.I. effect can be quite dramatic

If i Get the Correct percentage of water Injection(ive read its like 10%-20%)Will my Feuling map need to be changed/will the car need tuning when adding just WI?(current map is 100% Rock Solid)

There is no such thing as a universal 'correct percentage'
It all depends on what you are trying to achieve and what your pre-WI engine balance is like.
10-20% water to fuel ratio is used often under full boost to supress detonation that might otherwise occur.
Cylinder distribution is also very important.

Will WI improve engine life?

Under certain conditions, YES
If your engine was on the edge of detonation and the WI stops it from damaging itself, then YES
