Bossho ran the Dyno Port pipe and Y pipe on his this year and it made a BIG difference. He ran the stock silencer and did not need a PC, we ride the same areas you do so I think you should be all set. I would like to do that as well as the PAR head to get the mid/low end bump as well. Time will tell.

you have to run a power commander if you get exhaust on the pro/assault.
Your statement is misleading, the Dyno-port pipe for one (and may well be others) does not need any tweaking of the stock fuel mapping to run reliably. However it may be beneficial for optimum performance to be able to tweak it.
let me know what you go with and how it works i'm going to do the same thing i'm leaning towards the slp stuff ,i want to wait till i can ride before i pop for it

if you run dyno port,run his full system,y-pipe,pipe+can,YOU DO NOT NEED A F-ING FUEL CONTROLLER on this system over 7000 ft,i have this setup on a 2011 pro 163 w/hhbig intake, w/ no fuel cont. i run 8500-10500 ft. this setup kicks ***,runs strong all the through the trottle, keep stock head on,this thing runs stronger than aftermarket heads,and is more dependable

well i didn't know about dynoport...and exactly how many of us ride above 7000 ft constantly? I ride between 3000-6000 ft and i was told with my riding, i will need to run a fuel controller...
i only ride between 2500-4000 feet.
#1. Same as others said, I ride 0-3000ft
#2. Full pipe system SHOULD run stronger than a head, but where did you get the dependable part??
Thanks.
This one won't void your warranty..problem is you have to get the guy that designed the CFI2 800 twin to give it up.
Anyone have experience with both Dynoport and SLP? Not adding a fuel controller does sound appealing because of the $$ savings but that is about it. I also wonder if a person ported their motor if the SLP wouldn't work better than the DP.
Edit
I guess Aaen also has a pipe for the Pro. Anyone have any experience with it? Aaen typically always produces.

I can assure you that is NOT the case. And, FWIW, Rich does as good a job porting motors as anyone on the planet - all his pipes REALLY perform when you port!!!
Have FUN!

i've been running a slp setup and my riding buddy has the dynoport setup. both of us are riding 11s and are running a 12.5:1 PA head. we ride from 0-5000 feet. i was running a pcV as prescribed my slp and my buddy wasn't using one. both run very well and are very comparable. the slp setup with the pcV was VERY same and towards the end of the season i pulled the pcV and just ran the stock mapping. we can only get 90 octane here so i was bumping my octane to about 92-93 to protect against detonation. sled ran great and the wash looked much better than with the pcV. i didn't want to have to bump my octane all of the time so i picked up an autotune to see what kind of map that produced. unfortunately work season got in the way and i never had a chance to try it out. we still have plenty of snow so i might try to get out this week to see how it does.

I run the same setup as you do now and have been thinking about pulling the pcv.
So if you manage to make a map for those elevations I would be very interested in hearing how they compare to the one supplied by SLP.

the slp map, imo, is WAY too rich/safe. imo. if it was me, as it was, pull the pcV and bump your octane a little. with either some av gas or klotz/torco additive. it runs better/crisper. but yeah, if i have a chance to run it with the autotune i'll post up the results.

Are you guys running SLP clutching recommendations too?
The reason I ask is the clutching (load) really dictates the engine management (pcV settings) that sled needs.
I know that SLP fuel recommendations are safe-safe but usually pretty close. It's like they come up with the final in field #'s and add 5 or 7% more for consumer use. I usually end up - 5% across the board with their maps with in a couple of rides on their Cat set-ups then add fuel down low for the lower engagement I like.
I'm trying to figure out if I should jump into my Pro with a stage two (later, about 100 miles LOL, to three) set-up or ride stock. On a Cat it is a no brainer because of the weight loss but with the Poo...??
Brew said it was close to a 8 to10 mph improvement. For a Doo guy to say that is pretty impressive LOL.
So,,, did you guys see a 8 to10mph (in a hill of course) improvement ? And, can you Alaska guys tell me what the cranking compression is on a broken in stock sled then with the aftermarket head? And, LOL, did you measure the squish on the stock head and then the aftermarket head?
