Well I must have jinxed myself with my reply. I've been running around 265-270rwkw for exactly a year now. Filled up with some P100 fuel about 2 weeks ago and car absolutely hauled ass, I swear it must have given me at least 15+ rwkw Anyway, nailed it today, manual mode, 1st gear, hauled up to 60kmh, then went nowhere and kept revving. Did it again, hauled up to around 60kmh, then car seemed to go nowhere and kept revving. Tell tale signs of a slipping box. Oh well, I've already booked it in for a rebuilt/strengthen in 4 weeks.
