i think the standard clutch can take a little over 300lb/ft. The DPF delete should be ok, but take this with a pinch of salt. If you worried about clutch slip, change the clutch later when the standard clutch starts to slip. With regards to power the the DPF will get between 225-245 bhp and the stardard clutch should be fine for that. most of the time it's the torque that kills a clutch.
for you information, if u had a big enough turbo, the engine block can handle 300bhp
