If you're running a "stock" setup, you really have no need to re-jet. If you de-install the AI system, then you've changed (slightly) the air flow to the combustion chamber & may require some change to the Main, & possibly, Pilot jets.
Basically, if you make any changes to the engine's air flow (input: air box &/or filter mods)(output: after-market exhaust), you will need to re-jet. Like Moe says, this will require some trial &/ error testing of different jet combinations.
The Dyno is only a tool to test & report the results of your changes.
