    Also, I didn't bother with a line out converter. Instead I got an amp (KAC-7205) that allows speaker level inputs which I spliced into the rear door speaker and it has signal sensing so you don't even have to run a on/off signal making the install super easy. Just run positive to the battery and ground to something in the trunk. Install took me about an hour.

    With the added sub you can turn the headunit bass setting way down to get rid of the muddiness from the mid range and liven up the whole system nicely. Speakers tend to work most efficiently when they only have to work in the small frequency range for which they were intended.

Eric said it is either waste gate flutter or the turbo getting close to the surge line, either way its normal and don't trip. LOL. Apparently these turbo's spool very quickly, almost too quickly to go 3/4 to WOT below 3k rpm in 3rd or higher. Although I get it the sound in 2nd sometimes too.

    bbrock171 have you experienced this at all? With TP or Cobb tunes?
    Sorry, little late on the reply here. I think I may know what you're talking about. It did kind of seem like a pulsing whistle that I had, which also seemed to make the car shudder too, especially at WOT below 3k. I sent Eric a datalog of my afternoon commute yesterday, and he sent me a "slight" adjustment which seems to run much smoother in those low RPM WOT situations now. I don't really notice the noise anymore either. I don't remember what it was like with the Cobb map. I ran it on my WRX, but with the new ride I had the Cobb map on for all of a day that it took to get an etune from Eric.

    Im looking at the cobb ap, I have purchased the k&n cai, It doesnt look like the cobb has a map for that- just stock and AEM and the SF is that true? Did I get the wrong intake?

    If you planned on using a Cobb base map, then yes.

    So that leaves me with the option of not using the K&N cai and getting the COBB ap or getting a AEM intake to go with the COBB ap.. What do you recommend I do

    You could probably sell the K&N for a slight discount from the new price and use that money to get the AEM, if you really want an intake. I don't know why you would not use it and let it sit around doing nothing.

    Another option is going opensource for your tune. I'm pretty sure Eric at Torqued Performance offers a map for the K&N intake.

    You use a Tactrix cable to connect a laptop to your ECU. Then you use a couple pieces of free software to flash a map and then datalog. That's the quick explanation, if I'm speaking a different language to you let me know

    If you already have a laptop you can use, then yes. I got my tactrix cable for like $140/150 iirc, new they are a bit more. There are different sources of maps. I bought from Torqued Performance, his stage 1 maps cost me $85.
