I love all the information on the site, it's awesome to be able to jump right in and see write-ups and stuff. I do have a couple questions I am hoping you can help with. I have done some searching and haven't been able to find the answers.

1) Installed a K&N air filter and noticed the much deeper noise but it seems to really get loud/noticeable around 4,000 rpm's (right at the limit of the break-in guidelines). So it would be quiet then briefly I would hear a ton of noise before I shifted gears and the rpm's drop. Does the noise generator tube only pipe sound in above a certain rpm? I had read it has a diaphragm which reminds me of vacuum secondaries on my older cars. Seems like it would make sense as at cruising speed you wouldn't want to be hearing the engine so much. I did end up removing the air cleaner assembly to make sure the K&N was fitting right and everything seems good there.

dont worry. probably just more noise from higher flowing filter element. if you really want to test out the sound generator unplug it or plug the hole in the firewall.

2) I was in manual mode on the highway in 6th gear and went to change lanes and accelerate around a slow poke and had no throttle response. Kind of freaked me out until I downshifted and got some power. Next day I was in traffic and was in 6th gear again and noticed if my rpm's fall below 1500 my throttle dies. Is this by design/programming? I realize its not typical of usage when you would be manual shifting. It works fine while in D mode.

these cars make almost no power down low. this engine is designed to be small displacement, high revving and fuel efficient.

Anyhow, appreciate any help you can offer and look forward to seeing you guys around. I am up in the Bellevue area (saw a white FR-S going through the intersection by 108th Ave NE this morning)!
