-Use grade 8 bolts. 
-Grease the tip of the puller and the threads. 
1.  Install the puller
2.  Tighten it as tight as possible. 
3.  Hit it with a big hammer. 
4.  Tighten it as tight as possible. 
5.  Leave it over night.  Then repeat steps 1 thru 5 until it comes off. 

I've taken off around 20 of these with this method, worked every time.  Be careful, when it pops off it can shoot off and land on the floor and break, or on your foot! 

Good Luck!

DO NOT USE HEAT it will destroy the electronics under the flywheel.  You could try using an impact but that never worked for me. just keep up with the above mentioned procedure is about all you can do I have tightened up some so tight I was sure they were going to break and they have popped apart. And it does hurt when they land on your foot!

when the puller is tight, make sure it is square with flywheel, helps loads

I was in a similar spot earlier this year. I used above technique and it would not come free. Finally on the next day, I used a larger sized hammer gave it one good wack and it popped off with considerable force throwing it to the ground. Future note, to avoid the flywheel projectile, thread the nut on a few turns to contain the flywheel when it releases.

leave the nut on to protect crank threads also
