I'm a new WRX owner (2013 CBS WRX sedan). I'm still adjusting to the car, and I want to treat her right. During "normal" acceleration, how high to you let the tach go before you shift from first to second? Does this change when you are trying to improve your gas mileage? How about when you go all out? I've been playing around with it, but I'm still not sure where the sweet spot is. I had it all worked out with my old 5 speed Tiburon, but this is a very different beast. All the later gears feel very intuitive.
