One thing I'm going to mention is throttle feathering. When going round not such a sharp bend or you want to slow down, how do the turbo boys go about doing this??

I mean, are you wary of this because of the boost going to come in and cause the back end to give way?

Just wondering as I normally try and keep above 4k rpm in a corner since max torque is just above that

Any less than 4k then I am on a dip in torque.
