Depends on the chip but generaly 40-45psi. Did this problem just start out of the blue?
I woud check out valvetrain first.

It should of told you in the directions of the chip where to set the fp.
70psi does not sound right?

Static set pressure plus 16lbs of boost. Ex.40lbs static plus 16 lbs boost=56lbs FP.Again your chip is a factor.
