Hey man are they the compete injector or just nozzels? I may be trying to buy them from you. My 6.7 started whitesmokeing so it's gettn trailerd to Hamilton diesel tomarrow to find out the problem. But I just put the mp8 stacked with my smarty and didn't drive it for a week and then drove it and powers still there but it white smokes at idol and black smokes more than ever at just regular everyday driveing. So hopefully it will be diognosed here in the next few days thanks.
