If your profile is correct and all you're controlling them with is an AFC, then it's way out of the AFC's correction range. Pulling your plugs will likely show plenty of black deposits and buildup. Injectors over 650cc should be controlled with something that will allow you to better adjust the deadtime and global settings such as DSM Link or a chipped EPROM ECU with injector compensation. Also, if you're really still running a 16G, why such large injectors?

Hope that helps,

Agreed, also, If thats not the deal, then they could be leaking. That would cause it to run crappy.
