TRX400X jetting with slip on?

Greetings and Happy Turkey Day!! I just acquired the HMF comp slip on exhaust. I ride in a range from 1000-5000 feet. Bike is bone stock. From what I have read, it looks like a 42 pilot and 155 main jet is prob the way to go if I don’t want to keep swapping the main for elevation. I don’t want to take my airbox lid off as the areas I ride can be rather wet and/or dusty. Does anybody have experience with jetting for just high flow slip on exhaust and that wide of an elevation range?
