Thanks for the reply Dave!
Maybe that is just the case heavy right foot syndrome haha, I scanned the car for codes with a snapon tool and there are no transmission codes present or speed sensor codes so maybe it is just the nature of having an open diff and the one wheel wants to spin up really fast causing the car to rev up quickly when I lose grip.
I have continental run flats on the rear and the pressures are correct, however the tread is nearing the low tread indicator so it might be time for some new boots soon! Any runflats you would recommend in particular?
