Start with the basics like-spark plugs regapped to .8mm-boost leakfrom there come trickier to diagnose problems-coils faulty-fuel pump rooted-fuel filter partially blocked-O2 sensor playing upHave you had it on a dyno to see what the boost and AFR's are like?Is that 10psi tune generic or custom?Take it to Ford or a tuner and see what codes come up.
