Whats a good timing for my KA-T setup?

[NJ3ndri]

hey guys i have a KA24DET. pretty much a fresh dtock rebuild with a ported head. cometic headgasket and arp studs. im running about 18psi on a t28 turbo 550cc injectors 255 walbro and rs enthalpy tune.
SO I was wondering what everyone else is keeping their timing at around this psi. i was told about 15-20 Base

I'd be worrying about what my next turbo would be seeing that that t28 won't last long at 18lbs
