Yea, crappy but true. Fueling will have to be tuned with as you go to different areas. They differ in temp, humidity, barometric pressure, etc so the fueling has to be adjusted.
The clutching, fueling go hand in hand together and they have to be tuned together. If one is off just a bit, then the other won't perform as it should and you will get sadness on the hill.
For example, if you have a clutch system that only pulls 7500 rpm on a big expensive 12 hr drive sled trip in a new area you have never been to, you have to spend the day clutching to get the clutches to work for the area and type of riding you. Even if your fueling doesn't have to be tuned, you must work on your clutch. To get the sled running close, not even perfect, you need about 10 lbs of tools, springs, weights and room on your sled. You never know what you need so you have pack every little trinket that you might need.
Throw in the tuning of your fueling but you can't get the fueling correct because the clutching won't allow you rev, you now have 2 issues to deal with. Some people have no clue about either of these things so they are dead in the water, really depressed because their stock sled buddies are having so much fun exploring the new area while turbo tommy sits on the packed trail cuz he has the turbo blahs and gets stuck when he goes off the trail. The turbo company can't help you because they may not have ridden the area where you are so they don't know where to start. Clutching or fueling wise. The local dealer can't help because he didnt install the turbo and doesn't know the components. Add the fact that he is either sledding or so slammed repairing sleds that he doesn't have time to help someone tune over the phone for free.
Add in that each sled weighs different, the riders weight is different, the air is different each day, snow is different and you are really on your own.
It can be done if you wanna dedicate the time to learning how the systems work together and it's really not that hard. Tons of info here on the forums. There are guys that have turbos that work but they have spent the time to tune.
Ya, guys will tell you, "I'm pull and go, pump gas all day long." just like powerfuldodge on this thread, he says he has never had detonation. Then u watch his video and he dets twice in three minutes. He either didn't know what det is, or he is in denial. If he keeps riding a detonating sled, he is due for a new motor and turbo as the ringland will break off, go through the motor, through the turbo and hello another 5 grand. Then, you see the turbo system or sled on the classifieds.
I'm not trying to be Debbbie downer for you but I'm just laying it out for you so you can make your own decision as to what turbo ownership is like. Myself, I like wrenching, thinking and making things work well so not a problem.
People downplay things by saying things like "runs flawless except for a small stumble", "I'm 90% there," "just a bit of tuning left to do," "one small issue to take care of," "the dealer just has to take care a small issue for me," etc. These types are in denial. The sled isn't working the way it should be. That "small tuning issue" is a major pain when it cause you to get stuck at the worst time. It ruins trips. It ruins your fun. Especially if you Paid 7-10k for turbo system.
If you go into a turbo system eyes wide open and you know what's in store for you, then it can be fun and you can have a turbo that will work. As a matter of fact, I'm going to my shop rt now to do some work on my turbo sled.
Cheers!
