Sounds a little extreme in that description. By "turbo line", are you
referring to one of the CAC tubes or the oil line?
As far as the exhaust mods (and only the exhaust mods)... no. For "odd"
failures, I have seen one turbo with a broken shaft... the turbine was too
beat up to tell if the thing had gotten hot enough to straighten the fins
but it was a "different" colour from what we're used to... this truck had
the factory exhaust. I've seen CAC tubes blow off the engine end (both hot
and cold side) - this is *usually* attributable to assembly without ensuring
the surfaces are clean and dry or insufficient torque on the band clamps.
Occasionally, we'll see a faulty VGT actuator or stuck turbocharger vanes
that can result in an overboost... stuck vanes is the most common in our
area and is a combination of poor quality fuel (a little bit) but mostly
extended idling. Of course, this is also assuming the EGR valve is connected
AND functioning properly (again, the largest problem with these is extended
I can understand your frustration but your one sentence is a little skimpy
for forming any meaningful opinion.
Early in the process, the programming crew came out with some bad patches
for the PCM software... seemed like the flash would fix one concern and
create two new ones to replace it. The latest flash is good and addresses
some EgR and cold start/run issues.
The biggest downside of big pipes is that they can crowd an already crowed
area making some service or repair operations more difficult than they need
to be. Also, some dealers have a zero modification tolerance... some don't
mind pipes and properly installed guages... I understand there are even some
that turn a blind eye to any and all mods - as long as truck and mod were
both purchased from them.

What gasping sound... you haven't mentioned that.... when does it occur? Are
there any other symptoms? What parts did the dealer replace? What were the
symptoms before these parts were replaced? These are extremely complicated
trucks and require much more info than is being offered to even come up with
an educated guess.
Thank you so very much for info.....
I was vague as I was trying to make since as to what Supervisor had to
1st - No power and black smoke ---replaced EGR valve and Flashed.
2nd - Blew turbo line on back of motor on turbo itself..melted hole in
protective mat on hood. -----replaced line and replaced mat.

Highway Patrol. ---- replace EGR valve.
4th - Towed 18' toyhauler w/ 2 125 motorcycles (small load) over Donner
Summit --- max speed 45 mph...when I took foot off of accelerator I heard
a gasping sound(almost as if something was collapsing)... black

EGR valve and said that everything was good. No codes showed engine got

I have 26,000 miles and installed 4" magnaflo exhaust the day I purchased
it from a reputable shop. Never had any problem until the past 2.5 months.
Now no one knows what is going on and it's just easier to say that it's the
exhaust fault...When asked why it has never caused problems before...they
What do I do now.... I am afraid to drive it.... PLEASE HELP....
