Many thanks that's an impressive curve

I have GTX2867R from the previous engine so I am 50/50 whether to fit this or keep it std then fit the Gtx later once it's all working but the cars built for 450bhp

That torque jump I am sure can be smoothed out with mapping / boost control, plus I have RWD and an LSD

Simon told me not to use the wideband, maybe for that reason. I will run one but not for mapping

If you fit the efr what will you do for fueling as it seems your power output is the limit of the injectors and HPFP

So 270 wbhp is about 320bhp fly?
