Turning up my timing tuesday what would you bump it up?

Yep... From the looks of your sig I don't see rings, or studs. 20* will blow that thing faster than a fat girl on Bill Clinton. I'd go 16*, 16.5 or 17* if you feel lucky. That 66mm Turbo is keeping your drive pressures low, but timing effects in cylinder pressures a lot more than it does drive pressures (exhaust manifold pressure).
Once you go to studs, you could run 18* or more, and with o-rings, and studs I've seen guys run 25*, although I never would without a copper gasket.

Yeah, actually, 2500HD is right. If you're running 50PSI, you should have blown the stock HG already, but if you bump the timing you could drop your wastegate pressure a good 10-15psi and still have the same EGT's probably. The timing would make up for the lower boost, and you'd run better at higher RPM's like when you install that 4k GSK, .
