I'm curious on the answers as well.

As far as ramifications, you could end up replacing cams, rockers, lifters, etc. Could even be worse,my boss grenaded his 5.3 at around 40k miles because of a stuck lifter. GM replaced the motor.

That's not something I want to do out of my own pocket.

Does anybody have a recommendation for a mechanic in the Ft. Hood area? I live in Copperas Cove, but am willing to go to someone who is reliable and does the job right.

I got a 16. The turbo issue was fixed in 15. I know the cold side pipe could blow. I know the problems with DEF. Those are all more solvable than dropping a new crate motor in that ****ing '14 GMC 1500 that I had. GM was only going to keep putting in new lifters.

Oh no one told you about the CP4 injector pump that could grenade and wreck your entire fuel system including injectors??

Dont buy fuel from shady places and change your fuel filters and drain your Water Separator and you'll be fine.

If you're that paranoid, you can get the disaster prevention kit for a few hundo.

I added a lift pump with a fuel filter and a water separator.

Truck runs way better, acceleration is much better and I am averaging 4mpg higher, worth it.

Yea it threw a code and when I pulled it the code was "Service Emmissions System". Decided it was time to delete rather than jack with the stealership ($600 just to run a DPF "clean out burn"!!) over and over.

I just rolled over 60k. Only had the kit on for 5k or so but truck seems to run a lot better.

So far so good. I'm not daily driving the truck so
I haven't run any mileage calculations or anything. But it definitely runs a hell of a lot stronger with the Range plug-in - it's got noticeably more power even comparing to V8 mode without plugin.
