Default Data slow down from GPE to Sense 6

Hi... I recently switched from a stock GPE to Sense 6 (Slightly Sense 6 Rom). My phone has latest firmware (6.09.401.5) and AT&T Radio (Radio_4T.24.3218.09_10.26.1718.01L) and I am on AT&T.

One GPE in the same spot... I was getting 15-20MB down reliably. Now on Sense 6... I haven't been able to get above 5MB down anywhere. I can get almost 10MB up.

I've tried a bunch of different APN's from: http://forum.xda-developers.com/show....php?t=2172110

Any ideas how to get back to faster data down?

Thanks!
