I see you have an Xcal 3...but who's tune? You should go with Bama...tell him to have it shift at 6200 (his normally shift at 5900).

If you want to see some videos of my auto w/3.73's smoking my buddy's manual, go to the drivetrain performance section and you'll see my thread. If you have a good tune, you should be low 13's. That's what my ET calculated out to...13.08 to be exact. I think it's kinda quick for my mods..but, I'm just going by what the conversion chart said.
