weird hesitation at 3800 rpm

im getting a weird hesitation at 3800 rpm, where any time i rev past that engine speed, no matter the load, the engine leans out slightly and hesitates. I logged it, and dont see anything out of the ordinary. everything looks good, not even any missed CAS teeth counts. anybody else have this problem?

im running just two injectors on sequential mode, staging disabled. my guess is causing it is maybe their is a fuel pulsation problem at that rpm?

That's probably when your aux ports are opening up

Post your map and logs. Log triggers since last home, AFR, TPS, CLT, IAT, RPM, primary and secondary injector pulse width.

I don't see it. I'd try turning off closed loop and throttle pump, independently of each other, to see if that makes a difference.

Check your trigger and home filter levels, had the same problem. Trigger levels were set to 0. Changed to trigger filter level to 1 and home filter level to 3.
