just installed pcv on my 09 d8 155.put about 20 miles on it and all the problems i had after the 2010 update are GONE!!!when i got my sled back it had the midrange bog,a tip in hesitation,random backfires and had to hold the throttle to get it to start about half the time.after reading posts about how much people were liking them and talking to dynotech jim i decided to buy one and just like that i have a perfectly running sled.i was optimistic to say the least but the first mod i would suggest to any 800 cfi owner would be the pcv.i know we shouldent HAVE to buy it to get our 800s to run correctly but i would buy it again in a heartbeat!!!big props to dynojet and dynotech jim!!!i ran 8200,8250 all day mostly all swamps(need snow!) up her in alaska.it has made my d8 what i thought it would be when i bought it!
