there is more wires on the srt ecu box than places to connect! is it right to take two of the wires from srt ecu together and put it along with one connector? make sencse?

Sorry to wake up this tread but I just installed my SRT intake and have the exact same issue - the car idles very low and is misfiring, when you give it gas off idle it bogs out and/or pops through the intake - at higher RPM you can floor it and it goes but otherwise runs like crap.

Anyone else find out what was wrong?

Did you only install the intake or did you also get the ECU that goes with it. If you don't have the ECU the intake is scrap and won't work with you car period
