MotorVac EGR DieselTune™ EGR Cleaning Tool For Diesel EGR System Cleaning on the intake and exhaust sides of the EGR valve and cooler. EGR Systems can become clogged with carbon deposits that affect fuel economy and performance of a diesel vehicle.
Do you need to clean your EGR valve?Since the 1960s, vehicle manufacturers have installed Exhaust Gas Recirculation (EGR) valves to reduce nitrous oxide (NOX) emissions. The EGR valve recirculates a small amount of exhaust into the combustion cycle.
The warmth of the exhaust lets the combustion chambers warm up quickly, while the spent, inert gases keep the chambers from getting too hot when the engine fully warms up. Whether mechanical or electronic, EGR valves open and close to control the gas flow. If left open, the excess vacuum will cause the engine to act like it wants to stall, idling roughly or surging. If the valve stays closed, detonation could occur in the combustion chambers; this knocking or pinging will lower mileage and the lifespan of the engine. To smooth a rough idle or hesitant or surging acceleration, and reduce knocking, clean your EGR valve.In diesel engines, fouling as a result of soot accumulation and depositing occurs as a result of driving at low revs, eco driving or from making short journeys. If fouling occurs anywhere in the diesel engine, the dirt quickly spreads through the entire intake system, as a result of which the engine starts to run irregularly and eventually it even cuts out. This dirt does not go away of its own accord or from regular motorway driving.
The intake system must therefore be pointedly and preventively cleaned. Instructions. Start the engine and let it warm up. Remove a flexible hose in the air intake system as close to the air intake manifold as possible. Let the engine run at 2000 rpm. With a warm engine, spray EGR cleaner, using the pipe supplied, into the air intake manifold, ensuring as much of the spray as possible enters the engine.
Spray in short intervals to avoid uncontrolled rise of rpm and diesel knocking. After each spray, wait until the rpm returns to idle before continuing.
If necessary accelerate to avoid engine stalling. Continue this process until the entire contents of the aerosol are consumed. Let the engine run at idle for a few minutes. Refit the flexible hose. After this idling period, accelerate the engine several times or drive the car for 3 to 6 miles. Do not exceed 3000 rpm.
Before stopping the engine, let it run again for at least, 1 minuteTips & WarningsThe spray can also be used to directly clean the EGR valve. Before thinking to change your EGR ValveTry Carbon Cleaning!To save money and resolve the problem.Preventive engine cleaning enables you to restore engine parts rather than replacing them, thereby saving vehicle owners on costly parts, such as a new turbocharger ($ 1.350 - 3.100), catalytic converter ($ 600 - 2.000), DPF ($ 600 - 2.000) or EGR valve ($ 370 - 500).These problems result mainly from poor combustion, which stifles the engine.So before replacing your engine parts, try Carbon Cleaning. A dirty engine as the result of carbon deposits is the new threat to vehicle performance.
Cost depends on what you get. For a full delete you probly won't find it for less than $3000.
The best way to do it is to install block off plates inline with the egr pipe. Your dpf and doc will be removed and cored out then re-installed. Def tank is drained and flushed then tuning is installed. You will not have any warning lamps or indications on the dash that the system is not functional. No the tuning is not able to be turned on or off with a personal computer.
That is the best way to keep DOT off your back. Where are you located? If your in the US and a dealer is holding back an annual inspection based on engine data then it sounds like they are fishing for repair work.Anybody that plugs into your truck would see no malfunction indicators. (i.e. check engine light). If you were to read live data a good tech would pick up on the values for Nox sensors as being below what they should. So to answer your question, yes if a tech is looking for it they will find it. Most,including DOT's, don't go past checking for fault codes. What about the variable geometry turbo (VGT), can you put a regular one in its place?I doubt that!
That would throw up a huge red flag! Discrete is the way to go! VGT Is really not that big an issue as all the other junk,Actually VgT has some benefits to the engine brake and so on! As for the dpf delete and it not being noticeable you don't have to have a trained eye to see a black stack!( Codes Or No codes ) Don't kid your self These engines smoke the soot is trapped and removed Remove the dpf and you will see the smoke! REMEMBER your removing it for OFF Road use!Edited November 24, 2016 by fjh.
For annual inspections in Ontario it's not quite being checked to any extreme but if a shop sees that the exhaust after treatment system has been tampered with they can withold signing a safety but most won't even take it in the shop. Currently the Ontario gov is writing legislation to include inspecting the federally regulated exhaust after system with the annual inspection.
Tampering or removing a factory emission system is enough to have the plates pulled on a road side DOT inspection which is also enough to fail an annual. it's not detailed section of the annual yet but as a licensed truck mechanic in Ontario I've been warned it's coming. Canada has already rewritten the glider kit rules to stop new trucks (gliders) from being equipped with older emission engines. Mr Diesel spec.fill your boots while you can. Lots of dealers are refusing to work on deleted trucks. While I agree with the delete and it's benefits, I fell bad for the customers that will have to switch back in the coming years in Ontario.Edited November 25, 2016 by bbigrig. I doubt that!

When VGt First came out on the AC engine except for the FACT the turbos kept blowing up the performance was awesome They had the wheel speed programed at 32 to 35 thousand and the the engine had 10 psi boost at idle!
So when you added fuel to the mix You had instant Clean power! However They were unable to keep turbos on for a week with out them scattering! Somthing had to give they reduced the the wheel speed at idle to 22 thousand and almost 0 -2 boost at idle the turbos lived alot longer however then suffered from lag some what. In some ways I wish the VGT Was offered earlier PRE EGR would have been an interesting combo with a none egr engine Nice fast spool up and a decent clean burn and no wasted fuel!

Then finally the new turbo came out and it along with a new engine data file solved the issue.
I think we still had one of those original turbos new in the box some where.
