My guesses...bad injectors, vacuum leak and/or needs to go one step colder on plugs due to having a tune. Search feature is your friend, these issues are nothing new and have already been discussed. You'll resolve this much quicker doing your own homework vs posting and then waiting for us to do it for you.

pull the spark plugs from cyl 6 and 8, if they smell like gas then its a leaky\bad injector, could be as simple as bad coils or plugs, swap the coils from 6 and 8 to other cyl's and see if the misfires fallow them.

Any updates? I was getting some of the same codes...if you clear them and the truck still runs like shit on cold idle, it's safe to say the injectors are shot as that's whathappened to me. The boost pressure sensor code and Reduced Power Warning on the iDrive stopped when I deleted the vacuum line running from the passenger fender to the rear exhaust valves.

Pull the plugs and move the coil packs and reset the codes before doing so...it'll take 30 min and you can save yourself $100+ per hour shop rate.
