I did a search but could'nt figure it out. From what I found 14lbs
is safe on stock internals with the right tune. OK, so here is my question. I am looking to run 14lbs of boost. Here is a list of mods so far. I see 10-10.5lbs on my boost gauge now.

Airaid intake, NGK tr6 plugs, 170 thermo, 2.80 upper(is on now) Also have 2.93, Bassani cat back etc.

I just bought the FTVB and 4x4 pan. I am looking to get the Predator and a lower pulley.

What size lower should I do and with what upper 2.93 or 2.80 to get 14lbs? Who would be good to tune it I live in NY?
