Evasive will still report a 429 Too Many Requests as it has immediate discretion. This is a result of a plugin repeatedly sending requests without a cooldown period, and gets worse the more performant the install is - funnily enough.
You have two immediate solutions, Toolbox for ApisCP, a plugin developed by @anatoli to sidestep these throttles for logged-in users, or overriding the throttle limits entirely.
Lastly, you can bypass this by setting throttle values remarkably high or bypassing specific URL filters. Ideally there should be a deadline to persist every setInterval() ms rather than basing off setTimeout - or ignoring it entirely.
