Hi Guys,

I've got a 2007 WRX Wagon with about 10100 miles on it. I just got back from a three week trip for work and it feels like my car just got slow. In first and second gear boost kicks in a little later than what it used to but it's strong. In third and fourth it feels like there's no boost at all. I'm not sure if this is because I left 1 gallon of gas in it for three weeks and then filled it up when I got back. Or if there may be a problem with a sensor. Is it possible that sitting in central Illinois for 3 weeks crapped something out (I'm from Colorado and I'm not used to humidity)? Maybe I'm just imagining my car to be faster than it really is and the three weeks away is screwing with my mind. Whatever the problem, I would appreciate your input. Oh yeah, it's stock, so far.

Thanks for the input.
