Indeed it does, but only if I really bury the throttle in third at around 5000 revs.

If I keep the throttle about 80% open rather than flat out there's no real dramas in any gear, just epic acceleration. The Hartge unit itself only wakes up and boosts you if you squeeze the throttle more than about 60% and only then if it thinks the car can handle it.

However the overall sensation is that the car is lifting rather than digging in with wheel-to-ground contact feeling suspiciously light at all corners - reminds me a bit of the drifting sensation of a 4WD rally car on gravel, a wee bit scary.

Nothing a bit of extra aero couldn't help I suppose.

Thankfully the Michelin Pilot Super Sports they fit on these cars here in the UK are awesome with excellent grip compared to the Pirelli P Zeros I had on my Porsches and far, far superior to the awful run flats I had on my 130i M.
