Yesterday for the second time in 2 months I got the "Reduced Power, Clean Exhaust Filter" message. Message went away but check engine light is still on. This dang DPF has got to go with the quickness! I got the Banks with the Economind hoping the "Clean Tune" would be ok with the DPF but obviously not. I'm told I can keep the banks and run the Quad 2 on stock with DPF delete and a delete pipe. I am so sick of having DPF issues. Had problems on my 07 CTD and now this truck What happened to the good ol days when HD trucks were emissions exempt!!!!!
