I couldn't tell with mine. I almost think it idles a bit rougher.
At a stoplight it sits fine for a bit, then it begins to idle really rough. I think it may have to do with the AC compressor kicking in, but I haven't turned it off since it has been so dang hot. It goes away if i go to Neutral or Park.

Ground Wire Kit success! 
I finally installed my Mikochu uber Ground Wires today and it has made a big difference in the idle, it's now nice a smooth. Also my stereo is a bit crisper. I'm still waiting to see what it does for the lighting but a big thumbs up for Mikochu on this one!

I installed mine yesterday:
And was I surprised at how well it worked (not that I didn't trust you Mikochu), but my idle seems to be lower, like around 500 instead of 1000 and when my car shifts gears, it's a lot smoother. Not sure about the audio bonus some have claimed or the static... but it does seem to have helped.
And also waiting to see about the lights as well.

Installed the Kit last nite! Thx Mikochu!!! I used Black High Heat 6gauge wire throughout with black heatshrink (so OEM). Cold idle is now @800rpm warm idle is @500 rpm 
New OBX header dropped my idle to @500 rpm and i love it. Thx again Mikochu for the awesome DIY and pics keep it up. Next...ground the girls new tC...

Just built and installed a 7-point ground kit in my fiancee's '07 automatic tC. Kit took me an hour or so to build, install took about 40 minutes. I used these points to ground: body-head, body-block, body-alternator, head-coil pack 4,coil pack 4-battery ground, battery negative-body, transmission-body. We used 10.5' of Black 6gauge high-temp wire, with black heatshrink for an OEM look. Much better throttle response, stronger idle, no shudder when you start the car with the AC blowing, more stereo clarity...she loves it...and is convinced the shifts are smoother too, even at higher Rpm. All at a total cost of less than $40.00! Will post pics soon.

yo itsmistale2u, I got a cheap-o ($20) grounding kit from e-bay. Similar to this one (http://cgi.ebay.com/ebaymotors/04-05...spagenameZWDVW)
Following the instructions here on SL, it was super -easy to hook up.. did it make much of a difference? Ehhh, some days I think it did, some days I can't tell. I left the wires on just cause they mess with people (like at Jiffy Lube) that open the hood. "What are these tube things?" "Oh, those are for the freon cooled super charger.. bump them loose and the freon will freeze your arm off." Funny how that makes them real careful working on your box. I know, it's not nice to screw with people like that... but damn, it sure is fun.

It can't be that different on a tC... just use string to measure your wire lengths...go from body to block, block to #4 plug (or daisy chain all 4 plugs if you want), #4 to battery neg., neg to body...
