Took my 2005 auto to the track yesterday and ran a 13.07 at 107 mph. I've done the air box mod and had magnaflows and an x-pipe welded to the stock exhaust. I also have a preditor tune for what that's worth. It was about 70 deg at the time. Does this sound about normal? I was really wanting to get into the 12's but it just wasn't my night. Thanks for your comments.
