Disagree- if the pressure is set to 3-5psi, the contents of the keg will slowly 'outgas' and become almost flat. There's something else wrong. I keep all of my kegs at around 10-14psi and have no foaming problems.
Is this just the first pint you pour off, or is it continuous? If there's any part of the 'pour' side that is not fully refrigerated (like the tap) the first beer will always be foamy.
If not, then it could be that 13-15 is too high a level for your beers and is overcarbonating them, try a few psi less.
