I see a few potential issues.
First, have you checked for KR? The bogging is likely a large helping of KR trying to save your motor from the Kaboom.
3.2 pulley. This is something that takes a low compression L67 a lot of mods or IC to do successfully. You don't mention rockers, cam, headers and/or IC. Pulley up before it blows up. Say 4.3" type of pulley up.
MSD coil packs are well known for causing misfires at mid to high rpm. Sad as it seems the stockers were better suited for the motor. Literally I saw another post about MSD's causing issues this morning.
ZZP Tune.. one never knows what ZZP puts into the tune they send to you. Swarzkopf couldn't even start his SSM90 kit with the tune they sent him. Although I wouldn't necessarily discount the entire tune, it could be a factor. Might be worth asking ZZP what they did in it.
