Still stage 2. Totally factory car still retaining the DPF & Cats etc.
There is a lot more torque available midrange, but the question is - at what point will the gearbox break? This should be reliable 24/7 at 580ftlb as its only a little over ZF's quoted maximum torque figures for the box so i will leave that there I think.
The power at top end is limited purely by exhaust gas temp and the restrictions caused by the DPF and Catlysts.
