Did some air fuel changes and timing adjustments. It needs some more tweaking between 3k and 4k. I think I can fix that dip in torque. I'm also going to make some pulls starting at 1200rpm to get the bottom end of the curve fixed up. Since it's got a small verter in it (stock) I feel I should get that dialed in as well. I also have a couple other changes I'm going to make. I ported a stock throttle body last night and did some clean up as well as ordered an underdrive pulley. Once the motor is broken in fully I'll swap to a synthetic instead of the HD diesel oil I have in it now. I'm hoping to get it to 385rwhp and 375ftlbs. Then the fun begins with the bottle.
