Gotta Ask--Tuner

[timswi]

Lightly looking at a 2017 Chevy LTZ 2500 Duramax. Since it has aftermarket tail lights (why?) and some other stuff, I asked if it had a tuner. Dealer (honestly) said yes for MPG (What all people say)...Anyway..It has 21k on it and I certainly don't want to have a voided 100k warranty due to it having been tuned .

I think the warranty is shot--Opinions?

They are asking market for it, so no great deal although there might be some room on it--The truck is mint though. Thinking I should look elsewhere--Not sure I even need/want a diesel anyway since the 6.0 and the 6.6 have similar towing capacity and that's really what I'm after.

I would think the dealer could answer for the warranty after plugging into it. From what I understand the L5P was out for a while until anyone figured out how to get in it. Here is a link to a discussion on tuning it:

I cannot imagine wanting any more power than stock if using as a truck and not a hot rod.

It's at an Alpha-Romeo/Dodge dealer--Not sure if they'd have the software to know or not. I agree about more power, they have plenty enough already.

if you aren't sure, walk away. There's a reason why you get those warning signals going off in your head, and they made a lot of other trucks back in 2017.

I have had tuners on Ford trucks before but I have a dealer that looks the other way. I would look for a 6.0 motor, they are good engines and you say you don't need the diesel so why pay a ton of money for maintenance and IF the injectors go south on a duramax, it cost a pile of money to replace them. My buddy has one, he paid $4k for injectors, crazy.

Not close enough with any dealers to get away with a tuner but I feel the same way about gassers vs diesels...Seen people get pummeled in all brands when injectors etc go south. Stupid money. The 10k premium up front is stupid money too, unless you just gotta have it. No disrespect to the diesel lovers. I've had them and love them but the new stuff is a little scary.

I agree - the techs at a dealership have a hard enough time working on them with factory assistance. Don’t think I would want one out of warranty either. You will find an equal or better deal with some patience.

how much should a truck like this cost

They want $53k for it. Not a great bargain.

I'm amazed at how much they want for trucks these days. I bought a brand new F-350 CCLB Lariat diesel in 2007 for 35 grand, the same truck today is 65K, it's nuts. You have to be making money with it to own one or have/ make tons of money to afford one. The market will crash at some point. I read the other day the default rate on new vehicles is very high, is it any wonder.

I've got 2017 2500HD with the Duramax L5P. It has been great so far. I bought it with just under 14k on it. It now has a little over 18k. We don't drive it unless we are towing. From my understanding, these still can't be deleted and the only programmers that can be used on them are "inline." so in theory it should be able to be unplugged without leaving any footprint. BTW, I bought mine last June. It was right at 13 months old. It went into service May of 2017. It is only an LT, so it is missing several bells and whistles the LTZ would have, but I got it 46k. I then got a 7 year/100k bumper to bumper warranty for $1100. It still had the 2 free GM oil changes left on it. I just did the first one a couple weeks ago. I will do the second one April 30th even though it won't have many miles on this oil change.

I'd say you got a killer deal all the way around--Congrats!!

From what I have seen and read one of the biggest reasons for getting a tune is to shut the EGR systems down.
That will let the engine run much cleaner internally and the oil will stay cleaner.
The intake manifolds even get carboned up with soot from the egr.
My little ecodiesel has about the dirtiest looking oil I have ever seen in a motor, it gets dirty looking faster then
my old Oliver 1550 with the Rossa Master injection system did which had been turned up a bit.

 

[atsah]

I used mine to turn off the check engine light due to me removing the EGR valve and welding the cooler shut. And of course to add power, don't know if they still do but they detuned and left a lot of power on the table. My 7.3 444CI was a beast tuned up and never had any ill effects at all. If helped the 6.0's in a big way as well..

My SHO is tuned by Gearhead in TX, Matt does an awesome job with the ecoboost, adds 50hp to the 365 it already had.

Okay sorry for the hijack OP...

Everything I've read about the L5P. It is a different beast from an electronics standpoint than anything else ever produced. If we want to do secure computing, we use 128-bit encryption. I've heard that GM used 2048-bit encryption on the computer to these trucks - thus why no one has been able to delete them yet. They can only do the inline programmers. I've heard rumors that folks have been able to crack it and get into it, but have yet to actually see anything that says they have. Banks and everyone just says coming soon. And given the fine that BullyDog got socked with back in November, I don't know that any of them are too anxious to hop on that band wagon on these newer engines.

Edge got whacked a couple of years ago also. I think it was about 1/2 million dollars in fines.

From Hot Rod:
Earlier this week, Derive Systems was apprehended by the Environmental Protection Agency (EPA) for selling tuners under their SCT and Bully Dog subsidiaries that were in violation of the Clean Air Act. 330,000 units are claimed to be in violation. In addition to paying the $300,000 penalty, the company must spend an estimated $6.25 million to bring their products up to snuff.

SCT/Bully Dog Tuners Fined by the EPA for Clean Air Act Violations - Hot Rod Network

From the EPA:
(Washington, DC - January 17, 2013) - In a settlement with the United States on behalf of the U.S. Environmental Protection Agency, automotive electronics manufacturer Edge Products LLC (Edge) has agreed to pay a $500,000 civil penalty for manufacturing and selling electronic devices that allowed owners of model year 2007 and later diesel pickup trucks to remove emission controls from their vehicles. Diesel trucks that are not equipped with emission controls known as “diesel particulate filters” emit excess particulate matter (PM). When running, trucks without these types of controls leave behind a trail of dark, black smoke. PM is associated with a number of health problems, including respiratory and cardiovascular disease, chronic bronchitis, decreased lung function, and an increased risk of lung cancer.

If you羆*e interested in a like deal - PM me as I have not gotten nearly that good of an offer on trade towards a 3500HD.

1. Hard to believe the prvious owner traded it in without removing the tune and told the dealer.
2. Even harder to believe the dealer is aware of the tune and hasn't removed it.
3. Since the dealer admits it has a tune, EVEN IF REMOVED AND PUT BACK TO FACTORY WILL THEY HONOR THE FACTORY WARRANTY If something goes wrong if you buy it and they know it was tuned? If not then walk away.
4. Price seems a little high based on what jwstewar paid for his.

Problem is, it's an Alpha Romeo/Dodge dealer..The dealer called the previous owner and he said there was a tune in it, good for him and the dealer for being honest with me....Since it's not a GM dealer, I'm thinking I'm on my own. Price is higher because it's an LTZ. That adds some pesos.
