Sound Clip: Finally Got a Tune--MS4, TD's, 1-Chambers Well I finally got a tune and here's the idle clip after the tune. HUGE improvement!!! I think the idle is set at 860 rpm. Enjoy!
and here's one of the dyno runs:

I was looking at your other vids and noticed you have tips on there, but it looks dumped under the car. Do you have fake tips hanging back there? lol

Thanks everybody. Numbers don't seem to add up. Check it out here:

The exhaust is dumped but there are dummy corsa tips in the back.
I'm probably going to do something different with it because you can see both the dumps and the tips from behind the car. Drives me craaaaaazy. 
I may end up putting cutouts after the mufflers and then tailpipes...not sure yet.

checking out ur graph and seems like A/F ratio is high. kinda hard to tell but looks like around 14.x if it is I think its kinda high. plus on last pull the way he played with throttle and when he steps on it sounds like it's slipping--unlocked tq'd converter maybe. My suggestion is take it to the track and see/feel how it runs time wise, then go from there or u can go to a different dyno place and do a pull, them compare. did u dyno it before cam install?

You're going to make me change my setup again with that thing. Sounds wicked.
