Increase the hold time or the temperature. The time it takes to slump a piece depends upon the size of the glass and the span of the hole that the glass is slumping into. Smaller mold = smaller span = longer hold and/or higher temp. Personally, I slump at 1225, though some people slump at 1100 — just depends upon the mold.

My next advice is to dump the preprogrammed schedules and learn to program the kiln based on what you are doing. In fusing, one size does not fit all. Start with the schedules found on this site, and then adjust for your kiln. Keep a log book of firings.
