I don't see how a fuel system cleaner would help clean the intake.

You mentioned "hot tune" and "full delete". Is this correct? I believe you will need the off road tune if you are doing a full delete.

 

[97hmcs]

This is correct for the OFF ROAD tune but not the HOT TUNE. Hot Tune shuts down EGR but not the DEF. With Off Road tune you also need to remove DPF and replace section of exhaust system. When I have problems with my exhaust and DPF I will move to deleting these.

Not true. DEF is 100% off on the MY 2017 with the hot tune.

Oh.....so there is a difference in Hot Tune by model years? I missed the part where Juggernaught was talking about MY 2017

Yeah. It's only the 2017's that are different as far as the DEF goes.

so with the egr stage 2 kit installed and with GDE ,does this mean the def/dpf still work as usual? Wouldn't the regen process still dump unburned fuel into your crank case causing issues with engine and oil longevity? How much does the dual exhaust cost to keep the original look with the dual tips out the rear?

def/dpf still work as usual with GDE hot tune. exeption : on 2017 the def usage is completely eliminated (Thanks Kaz)
regen every 700-1000 miles instead of every 70-150 miles with stock tune.

It's possible for some unburnt fuel to enter the crankcase during a regen.

From the Owners Manual:

NOTE: It is possible for your oil level to be slightly
higher than a previous check. This would be due to diesel
fuel that may temporarily be in the crankcase due to
operation of the diesel particulate filter regeneration
strategy. This fuel will evaporate out under normal
operation.

I understand the regen process uses urea and diesel to burn off particulates in the dpf filter,any unused fuel is dumped into the crank case which is suppose to evaporate eventually.

As for the dual exhaust question,what I was referring to was the OFF ROAD TUNE ,it needs a new exhaust system from what I understand.

The DEF is not used during a regen. DEF is injected into the SCR downstream of the DPF

Lots of info. in the owners manual:

DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic Reduction
system to meet the very stringent diesel emissions
standards required by the Environmental Protection
Agency.
The purpose of the SCR system is to reduce levels of NOx
(oxides of nitrogen emitted from engines) that are harmful
to our health and the environment to a near-zero level.
Small quantities of Diesel Exhaust Fluid (DEF) is injected
into the exhaust upstream of a catalyst where, when
vaporized, it converts smog-forming nitrogen oxides
(NOx) into harmless nitrogen (N2) and water vapor
(H2O), two natural components of the air we breathe.
You can operate with the comfort that your vehicle is
contributing to a cleaner, healthier world environment
for this and generations to come
