Need Help Scaling Photoshop Effect to...

Hi Friends,



Working on a cool PS web tutorial and it worked as promised. Here is the site link: http://www.photoshopessentials.com/photoshop-text/text-effects/light-burst/



This tutorial is done at 640x480, 72 dpi.



I want to make a larger, higher-rez version for print (t-shirt, mug, hats, on cafepress). When I tried the tutorial with PS set at 300 dpi and 15'' page size, the effect did not work as shown. In particular, I had trouble with the ''wind'' application in steps 14-16: http://www.photoshopessentials.com/photoshop-text/text-effects/light-burst/page -5.php



Perhaps, due to the higher rez, the wind filter did not distort the text as shown in the tutorial. It was much less pronounced. Repeated applications of ''wind'' did not salvage the effect.



Can anyone help me attain this tutorial effect at higher resolution?



Hope I've been clear enough here. Don't hesitate to ask for clarification.



Thank you.
