You said muffler was modified, check to make sure part of it inside did not come loose and partially plug exhaust.

Are we talking about a 03 RX1? If we are, stock is as I said before 135 mains and 17.5 pilot jets not 25 pilots your dealer is wrong. What was the problem we cant help you unless you give us accurate data. Check the stock settings yourself at the top of each page there is a TY Tech link click on it then snowmobile then stock settings.

You don't have to mod the air box. The muffler being gutted is not really changing anything. Well,it is making it loud, but you will not really get any extra out of it. 17.5 is stock for sea level. Enjoy the sled.

Your jets are bigger than mine and I'm running 240 hp
So I would go stock in your case.

I am running the 17.5 stock idle jets on mine with my air box mod with no problems, others are using 20's with my air box mod with good results as well.
