In case any one is using/building a PIC programmer and wondering what would happen if one uses a Vpp higher than the max. limit stated on the datasheet(e.g. using 13V Vpp on a 16F914 with max. VIHH of 12V), the follow postings from the Microchip forum would give an insight into that. It is very likely that the PIC would die after being programmed 5-10 times. The guy is using two original ICD2s and different batch of PICs from Microchip. Check the posting dated 24 Sept 2005 at the bottom of the thread.

Do not let Vpp exceed datasheet VIHH limit.
