I always read how a banks system will not void your warranty. IMO the truth is it can and does. If Banks still advertises this,Id call them first,see if they will honor it,or pay for the pump,and all future claims that are within the 3/36 or ext coverage. If they answer no,time to go to court. Banks also claims there exhaust brake adds 15-30 hp,on the Ram CTD which is an outright lie,that defies the laws of phsics so I dont believe anything they say anyhow.
