After applying this mod through CWM your dialpad vibration will be equal to navbar buttons vibration. So, vibration feedback will half decreased.
As for now I'll add only version for .retail.en.US rom (which is 4.4.3). If you have different ROM (region/android version) you can give a try with 443_1032_US_vibr.zip on your own risk (make backup of dialer.apk & .odex firsrt).
Or you can request this mod for your ROM by posting in this thread your files (dialer.apk & dialer.odex) and providing some info about ROM you're using (in case if somebody who have the same ROM want to test it).
