I just got the same 2750 on my catless supercharged S65. Any resolution to this issue? Thanks.

I had the same code, along with an intermittent ABS,BRAKE,traction control light, on my catless Harrop S/C set up. I swapped the passenger O2 sensor and cleared the code. The check engine light went out, the ABS,BRAKE,traction lights are still on and the car is breaking up between 1500-2000 RPM under normal accel and 3-4K WOT. No code still.
