Be careful what BAMA tune you run if you are only putting in 87...
Personally I agree with Sean. I put in 93 every fill up even when my 2011 5.0 was bone stock. If you read the factory manual it is what Ford recommends anytime you are driving any other way other than a 90 year old person in a hybrid.... Which only maybe 1% of Mustang owners do and maybe .05% of forum members do. So my advice along with everyone else's your next fill up should be 93. If it isn't please refrain from asking questions like what is my HP with X mods as with 87 it doesn't matter as it isn't the best your car can do and it is actually bad for a modded motor when even the stock motor recommends 93.
Just my .02 and opinion....
Also on a side note be on the listen/look out for the PING PING PING noise because it is only a matter of time if you are modding and hot rodding around on 87... With that said it is like mentioned above with a tune and the mods you have factory warranty has left the building at this point.

(I have owned a few non Mustang cars over the years as well, but always try to have a Mustang with it or come quickly back to a Mustang!)
