I have a 05 which is basically the same sled, bought it last year with less then 900 miles on it and other then the usual mods and personalization things we all Doo you should read this-->
http://www.dootalk.com/forums/index.php?sh...=117364&hl= -- its 21 pages of carb talk and the short version is just about everybody does the 07 pilot and needle update and some do the remap also. Go right to page 20 for the DEALER BULLETIN. Anyway I had a slight high idle hang up till I bliped the throttle and the update goes from stock 17.5's to 20's for pilots and eliminates that hanging idle and the needle update makes it run a tad richer in the mid-range to prevent piston meltdown and for the lousy few bucks it costs its well worth the peace of mind you'll gain, I did NOT do the remap and have not noticed any extra fuel usage. There are a few people on here selling "kits" to do it, though I highly recommend using the right parts with no shims, get the correct needles & pilots right from ski-doo, the part numbers are in the article for everything needed and if you do it yourself its a easy job and takes about an hour. Other then that, you have a SUPER SLED I love mine.
20 pilots are not part of any organized update from BRP, it is something that many of us have chosen to run to get more fuel at idle, and then adding more fuel in the midrange through an extra or bigger shim on the needle. choice is yours to go bigger on the mains as well
the update you've done is not complete until you flash the ECM, I suggest you do that because the program you have now is designed for a different needle jet. or just put a .020 + stock .030 shims in the stock needle, with your 20pilots and 2 turns on the screws. consider bumping to 450mains as well by doing some WOT plug chops.
