most people are still running the original Fuel pressure relief. the thing wears out in 100k miles and who knows what fuel pressure is unless you have a fp gauge. the brass poppet gets worn out, and the orings are shot.
not to mention some folks (my dad) never change their fuel filter
but your hpop could be having trouble keeping up as well.
php tunes are programmed to not defuel, they still set the light for overboost though.
