there is a lot of good info on here. and dont be afraid to ask dumb questions.
i would keep it, i love my 6.0 but thats me
some basic upgrades...
-4" MBRP turbo back exhaust no cat. truck will run cooler, and sound awesome. plus you most likely will pick up some mileage. i got mine for about $340 delivered to my door
-intake. either (search diy intake) or get an aftermarket one. NO K&N!!!!!!!!!!
- get yourself some gauges. Edge Products| Product
or some thing simmelar so you can keep any eye on things. especially your oil temp and coolant temps.
- drain the crap ford gold coolant!! & put in a coolant filter
-SCT X3 tuner with custom tunes..
i wouldn't worry about studs, unless you want to run high hp tunes.
egr delete is probably a good idea. but im waiting till mine goes before i delete it. same way with the studs.
if im forgetting anything some one else chime in..........
