The roads have been wet lately so I can't get a good "low-end" acceleration without boiling the tires. Still, my biggest suprise is how much noise the intake produced! I can see why a lot of people like the system (for the noise factor). I wish the spike in power was at a lower RPM (2500 would be nice) though.
Hopefully it'll dry up here soon and I can make some good 0-90 mph runs to get a better idea on what the difference is. I do miss the noise though
