That if you drive the car properly then the lag is minimaf, is you try to accelerate at 1500rpm then there will be lag just as if you try accelerating at 5krpm in a diesel its pretty pointless.
You have to adjust your driving style to suit the power delivery.
You do indeed, but this is not to everyones taste. The OP has posted the most bizarre request of any car with a turbo, which is ludicrous, as it seems that he probably doesnt even know how turbocharged cars drive. How can someone buy a car like that?
