Major Hesitation at 4000rpm under boost

I'm running an elite 1500.
I get a major hesitation at 4000rpm. Only happens if I'm boosting. If I boost under 4000 rpm, no hesitation. Could this be an injector staging problem?

Apologies, there's alot of data and config here so I didn't know where to start.. The injectors are ID 1050 primaries and secondaries. What do you need to point me in the right direction to fix? Below is my injector setup..

Are you running NSP software? 2nd stage "injections per cycle" should be 2. And i would setup the dead times per these tables.

Update the firmware and select Nexus style staging. Enter the proper injector flow and dead time info and you’ll be good.

I've tried the above. I updated the firmware and software to nsp. Checked the injector flow and dead times and switched to nexus style staging, but haven't resolved the issues. Is there anything else I should be checking/adjusting?

Yesterday I ran carb cleaner thru the injectors. Fixed the issue. These are low mileage injectors so I didn't think they'd be gummed up, but the car has been sitting for a bit so I guess that caused the issue.
