If i want to upgrade my truck and chip it and put injectors than the dual mass flywheel needs changed to a solid flywheel and new clutch assembly. Is that correct

Yes, the DMF is the weak link in the OEM clutch. A solid flywheel and upgraded clucth is needed for added power. Whether you need a single disc or dual disc depends on hp plans.

I really just want a mild chip or 60 hp injector tips? what do you think about the clutch options

A mild tune would be fine with a single disc SBC OFE. Much more than that would need a double disc for longevity.
