Increasing torque

Looking at my RR results (TDF rollers) it looks like my car has a fair bit less torque than others on here.

I have 150Nm peak after remap at ~5500rpm and only 125Nm at 2500rpm. Most other plots are peaking at 160Nm and have upto 150Nm at 2500rpm.

What could be causing this difference? My peak power is good at 191 ish after remap.

Car is standard engine wise + ITG filter
 
I've seen other graphs from TDF, all have higher torque, even those cars with lower power.

Rico, it was in august/september I think so yes ambient temps would have been fairly high but I'd expect that to affect power and torque equally.
