Hello, everyone. My name is Phillip, but I go by Neo in all of my online interactions. I just bought a white 2008 Chevy Impala SS. I also own a 2003 Chevy Impala. My new SS came fully loaded and the only mod on it so far is the K&N CAI. I'm interested to hear any suggestions you all may have for future upgrades and other such improvements. I have been toying with the idea of getting at the very least a tuner. You know, one of those devices that plugs into the computer and changes the performance characteristics of the vehicle. I love the performance of the engine, but if I could find something that could enable me too eek out a little extra power when needed or conversely improve my fuel economy the rest of the time, I'd be very interested. I have also given some thought to the idea of changing out the exhaust, but if the horsepower gain isn't worth the added cost and hassle, I might be persuaded against it. I came here because I figured if there was anyone that could offer insight, it'd be an online forum about the Impala. Anyway, it's nice to meet all of you and I look forward to future interactions with you and hope that I may be able to offer some of you insight from time to time as I expect you will me.
