Essentially yes, but indirectly. I only really use it for vocals and little blips and bloops but never a whole track- did it a few times with loops befier I made my own and it just sound poop.
what program did you use?

I'm curious though, why an extra 2-3bpm? Can you not just up the tempo a smidge
its the overall feel of the track. its at 140 at the moment i reckon it will sound better about 142ish.

to up the tempo id have to either time stretch 40 odd individual audio parts (which will take me till next year!!!) or else re-record 40 individual audio parts which is what i will probably do if ableton doesnt do the trick for me.
