And it was tuned conservatively at 20psi on 93oct. And it made 325hp/305tq on a dynojet. Knock value peaks at 20-30 during pulls on my PFC commander. I've only ran the setup on 14.5psi even though it was tuned for 20psi. Do those numbers sound about right??? And are those knock values something that I should really be concerned with???

PowerFC is set to warn you of any knock value over 60.
Honestly, I don't like anything over 15. That's just me. I've hit 50 before and hear no sign of pinging or detonation at all.
So fellas I need some new cams. I hear great things about JWT but I'm unsure which ones to get. Tax Season is stupid good to me this year. So I am upgrading a lot before finally heading back to the dyno for a better tune.
Heres a basic layout of my current mods
Apexi PFC D-Jetro W/Commander
Built bottom end SR20
Bone stock head
ISIS intake manifold
Tial MV-S 38mm wastegate
GT2871R .64
Currently running a rather large GReddy FMIC but i am switching to the PBM HMIC
Nismo 740cc injectors in a CS Fuel rail powered by a walbro 255
I may be missing something. But this is what I am getting before going back to the dyno-
Apexi AVCR
Competition Stage 4 clutch/flywheel
PBM HMIC with recirc'd BOV
New Apexi headgasket
ARP studs
Possible water/meth injection
And then the cams.
My ultimate goal is 400whp on pump.
Would S3 cams be good? Or a little overkill?
