Welcome to FTE, great place and even better people here.

I am new to 6.0 as well, all in all to keep it in good order its maintenance. New injectors and oil pump are a good start to not having big issues. From all the research I have done on these three things to do first. One is the blue spring upgrade, check health of FCIM, and clan egr. These three things seem to be main culprits of many probs. All are in tech folder and easy to do. while your there read the new owners thread. Lots of good info there I pretty much read everything there and printed out the no start trouble shooting to keep with me in truck.

Gratz on truck and good luck!
