Just drove a WRX for the first time, 2005 with about 7K miles. Very nice car. Love the AWD.
Under heavy throttle in 2nd gear it starts rushing at about 3000 but seems to go much flatter around 4000 or 4500. I asked the salesman and he said it (the ECU I assume) learns the driver's patterns and probably had been driven by someone who shifted at 4K. He said it would act different if I drove it a couple of thousand miles.
Does that make sense to the experts here?
