you guys can see my sig, I am still running stock timing. would you twelve valve guys say Im doing decent power, I have 3.54's. And also how much of a speed difference is there between a 3/4 ton and my dually? if they were the same setup?

I'm new to the p-pump world, but I would say stock timing with the fuel you have available is definitely wasting some HP. Stock timing did not have 3000+RPM in mind. That torque number is nuts, though!

as long as gears and tire size are the same no speed difference, i think thats what you were asking. advanced timing gained me probably 50-65 HP but mine had slipped some from stock, runs better at high RPM (2300+) now.

I was just curious if I am running decent HP for my setup really. Im a little scared to adjust the timing, is so I need to gate the turbo at 45 im thinkin. It will hit 50 now, but the stock timing keeps head pressure in check from what I understand
