No it is the standard PCV. If you watch the Go Pro I posted, the motor is being loaded a tiny bit too hard. I took the 73s out and put 71.5s in for the next ride. The sled ran real good before, but I thought I might need to play with the map just a bit. It would bog ever so slightly on occasion in certain on off throttle situations. I changed the weights and did not touch the map. Believe SLP and the other expert tuners when they say the clutching and map must work together. I am so happy with how it runs. Over the hood snow all day and never a hiccup.
