No real performance mods such as intercoolers. It has simply had a DPF delete and I believe was remapped to make that work. All other mods have been preventative such as swirl flap delete & turbo actuators.

(this remap was done 5 years ago fyi)

Your torque curve does look a little off.... 2,500rpm is where you see the turbo changeover so that dip is normal, but for me my torque peaked at 3250 rpm @ about 540 wheel torque and your have a dip before there. If your tune was done 5 years ago it might be time to update it. You may be hitting a torque limiter right there. Those are still good power numbers for what you have done... my dyno numbers were similar 348 wheel hp & 532 wheel torque. But I had a bad boost leak on my intake where I sandwiched two vacuum lines under the intake and I was on a Mustang dyno which reads lower.

Correct me if I'm wrong but I don't think the lines should cross, the dyno may be setup wrong or not properly calibrated.

Well isn't that why the left side is torque and the right side is hp?

The torque and hp lines typically don't cross because most dyno graphs scale tq and hp equally using the axis on the left hand side and our diesels don't spin up to 5252 rpm. Luke's dyno graph has a different scale for each (tq on left, hp on right), and thus the lines intersect at a lower rpm.
