Low Vacuum at Idle

Low Vacuum at Idle
At idle, I'm only seeing 14-15 inMg on the boost gauge, and 55kpa in TS. I've set the timing to 20*, AFRs are about 13.8 now. What would be some things to check for the cause of this? There are no vacuum leaks, timing belt is good, stock cams. I'm really lost as to what could be causing thing.
