    yep same, it revs a little then back to idle. Most cars do this, just SRT/Dodge finally gave us active exhaust that lets us hear it happen. When you have the older stock exhausts (14 and earlier) that exhaust ate most sound.

    15-1800 for about 10-12 seconds and then slowly idles down to around 1000 or a little less.

    It will make me smile too, if I know it's normal.

    Yes it does it after it hasn't been running for a day or so.

    It also when warmed up will start sorta like an older engine does when the timing is too far advanced . Is that normal. I've put gas in twice now first was 93 octane and today i filled it with 91.

    They're allot of stuff going on in that motor,, one of the big things is the fuel,,1/2 inch fuel lines adjusting fuel and air and timing. Very complex engine management..just smile and let it do its thing..
