Merc 260 efi high rpm issue

[aljero]

Hey guys. I hv a 260 efi ruck that is having an issue at 6k rpm’s and higher. Best explained it’s like dead shorting a coil out intermittently momentarily at over 6k. The switch boxes are new. Batteries are new and always kept on a tender plugs are new. Fuel pump is new the ACU is a brucato which is brand new as well. Any suggestions? 🤦*♂️
