Hello,

I love the car after the upgrade. It is a completely different beast. I actually have not done any major highway driving since the mods, so I can't really tell the mileage. My mileage in town is horrible, and always has been. I get right around 17-18 mpg in town, and that is what I got before, really. The car is obviously different, and noticeably faster. I do not have any empirical numbers on the HP, I would say, by feeling, more than 5, less than 20 from the tune, throttle body, and CAI together. In total, I spent right around $500 and I believe it was incredibly worth it. It was a project that I really wanted to do, and it was very rewarding!
