Little update...
It's looking like the power mods are hitting the torque limiter of the DSG, so I'm back to needing at least a torque de-limit, before I get some more urge from the car.
The wmi must be working as I used over half a bottle of it on the round trip to JKM.
Been out today, even though it was damp the car still managed a 1/4 mile in 14.1 at 103.5mph and that was off a 5.8 second 0-60 as grip was at a premium. Hopefully I'll be able to get to the pod or York soon.
