Default engine tune issue low idle

Hi guys I got a small tuning issue which I am not sure about running a picco
P7 evo2 in a 808 buggy, engine has plenty of zip down low and also up top but after wide open throttle and then off throttle my engine revs always drop below my idle speed then it comes back up withing a few seconds?is my bottom to rich or lean or something else so I can adjust it to return back to its good idle speed after full throttle?

Your high-speed needle is too rich. When you're at full throttle, the engine is getting too much fuel, which causes the engine to continue to run a little rich when you let off the throttle. It sounds like the low-speed needle is set correctly, and it just takes a second or two to burn off the extra fuel that was left in the engine after running on the high-speed needle.
