So, What Is Tony Stewart's Dead Weight Problem?

Today, Tony Stewart won the New Hampshire Sylvania 400 in Loudon, NH.
In the post race interview, he said he got rid of some dead weight. Not sure if it is in his personal life or professional life.
No information from ESPN, which televised the race.
From this web site, there are rumours about a girl friend breakup.: http://www.talk-sports.net/nascar/girlfriend.aspx/Tony_Stewart

One of life's great secrets for now.

Update from ESPN: Stewart was cryptic about the turnaround after he got out of the No. 14 Chevrolet at New Hampshire.
"We got rid of some dead weight earlier this week, so, it's made it a lot easier It's been a big weight lifted off our shoulders," he said, without explanation. "Sometimes you've got to make adjustments in your life, and we did that, and it's definitely helped this weekend for sure. These guys have never quit, man, these guys have never given up, and we've got a shot at this thing."
Pressed on the issue in the media center, Stewart declined to address it.
"We're just going to leave it at that," he said.
Whatever he meant, it seemed more personal than professional. Crew chief Darian Grubb said there were no personnel changes on the team.
"Maybe he's talking about me and I just don't know it yet," said Grubb, laughing.

I coul dnot find anythign on NASCAR.com
If he is talking about dumping his old girlfriend, man, that's cold.

Update 2: Just throwing this out there. earlier in the week, ESPN ran a story about how Tony Stewart was going to be no more Mr. Nice Guy while driving.

From ESPN today: OK, everybody sit down, shut up and hold on -- for another rocket ride with Tony Stewart to the top of NASCAR and, as usual on such rolls, into uncharted territory of cantankerous enigma.
Stewart threw somebody under the bus -- it just wasn't clear whom -- live on ESPN on Sunday, after winning his second straight Chase race and taking the points lead in the playoffs.
"We got rid of some dead weight earlier this week, so it made it a lot easier," he said in Victory Lane after pressuring Clint Bowyer in the waning stages of the Sylvania 300 until Bowyer ran out of gas with two laps remaining.
"It's been a big weight lifted off our shoulders," Stewart continued. "Sometimes you gotta make adjustments in your life. And we did that. And it's definitely helped this week for sure."
Pressed by ESPN's Vince Welch to elaborate, Stewart refused. So, my TV-side colleague Marty Smith and I agreed that the first one of us to get a question in during the lengthier postrace interview would meet that freight train head-on.
Meet your new Chase leader: Back-to-back race winner Tony Stewart.
I got a hand up first, and told Stewart that the track and the Internet were abuzz with curiosity about what he meant.
"We're just going to leave it at that," he said.
No we weren't. I tried to ask if this was a personal message, one-on-one, to somebody out there, but he stopped me in mid-sentence.
"You can't ask anything," he said. "It is what it is. That's all it was, is what you said. That's where we'll leave it."

The other possibility is this: Stewart has a wicked sense of humor. When he was in Las Vegas last December for the awards ceramony, he was on stage with the top 10 drivers of last year's Chase. He had everybody darn near rolling in the aisle laughing our butts off. This may be his way of humor, getting back at the press, or trying to get under other driver's skin.

Whatever it is, he certainly is making people talk.
