You won't see any compression loss until it's too late. Your sled does not need A fuel controller. Don't waste the money. Put in a fix kit and make sure you get the fuel map checked out. If you do some reading on here you can find out more about the map. I believe it's the April 2010 map.
Don't worry about the fuel controller just make sure the latest fuel map is loaded. Once you approach 1500-2000 miles put in that fix kit regardless of the warranty. That way you won't be picking up engine pieces when it grenades. And it will.
