Upgrading to BOSS 302 intake manifold, should I beef up auto tranny?

Hey guys, I have a 2011 5.0 and am looking at the BOSS 302 intake manifold. With a computer tune, the gains are supposed to be in the neighborhood of 50 hp and 40 lbft. However, I'm pretty sure the stock auto tranny can just barely handle the power already under the hood, so I'm somewhat weary about adding that much to it. Anyone with experience care to tell me if I need to beef up the tranny or not? Thanks.

All the dyno sheets I've seen point to about 25HP from 5,500 - 7,000RPM about 15HP from 2,000 to - 3,500 all other HP numbers are the same with 1-2HP I wouldn't sweat it. You auto trans torque capacity will be increased just by a good tune. I'd also add a cold air kit if you don't already have one.
