About 10,600, probably closer to 10,700. It feels like it hasn't lost anything, but I know the buildup on the valves are very gradual so you won't feel any difference from one day to the next. I haven'y had any trouble with a stumble or hesitation when WOT. I did just add an Airaid M.I.T. tube and it does feel more responsive. I'm not sure if it's all in my head or if it really did. Of course I know I won't feel any HP increase, just feels like there's better throttle response, kind of like when I installed the K&N intake kit on my 98. After installing I let it idle a few minutes and then drove for about 20 miles with all kinds of roads from city to interstate. So if I get a catch can I'll have to figure out hose lengths with the Airait M.I.T.
