Okay, so everyone on this board talks about this performance tuning. I just got a 2015 RT. Here are my questions:

1. Does it improve or limit gas mileage
2. Does it take away any warranty or lease deal (since I am leasing)
3. Is this something I can put on without any knowdge of cars and how long will it take
4. Will it sound better
5. how much for a basic package and can you send me a link on what to get for a 2015 RT AWD.
7. Is this the best option to improve MPG and performance at a cheap price with a lease
Thanks so much for your help

 

1. Tuners generally do not improve mileage because you will be constantly romping on it with the newfound power.
2. Tuner will not do anything bad. Might be a good idea time to "return to stock" if you take it in for any warranty work or dealer service.
3. Plugs into your obd port. Follow onscreen instructions. Not difficult at all.
4. It will do nothing for sound. It modifies engine tuning from the computer to optimize performance.
5. There are a couple out in the market. I suggest you visit the websites for pricing. Superchips, Diablo, maybe more.
7. (6). As stated, mileage is not the point of a tuner. Some come with mileage tunes but they are a waste. It is mainly for performance. You best mileage improvement will come from your right foot. If you are concerned with mileage, don't get a tuner. Invest the money in a less restrictive intake and exhaust. (This is probably not an option on a lease).

Good luck!

 

My experiences after installing the inTune DCX on my '12 R/T. The DCX comes with several different tunes, from mileage improvers to high power. I installed the highest power tune:

1. My highway mileage improved about 2 mpg. But you have to drive the same way to see it, and the tune I used requires premium fuel. Other tunes on the inTune do not.
2. Even if you return the tune to stock, dealers can see that a tune has been installed by tracking the number of times the 'puter has been flashed. Don't know how it would effect warranty.
3. Pretty easy to install/uninstall/modify after the first time.
4. My truck (also reported by others) did sound a bit more aggressive after the tune was installed. I don't think is is our imagination, change is subtle.
5. Can be found cheaper at some site-supporting vendors. http://www.diablosport.com/products/intune-dcx.html
7. The DCX comes with a mileage tune, don't know how well that works. As stated above, my highway mileage did improve with the "Diablo" tune. The Durango comes with a very effective intake and exhaust, don't expect much if any change in mpg especially for the $$$ spent.

Ive had a tuner (SCT) on one of my past F1fiddys. It came with an Eco, Performance and Tow tune. I had an CAI and Magnaflow full exhaust on the truck. I noticed nothing with any of the tunes loaded. Complete waste of money. I returned it to stock and sold the tuner after 2 or 3 months.
However, I have heard many people rave about a "Hemifever" tune for the RAM 1500s. I ve been very skeptical because Ive been down that road before with no results. Even though there had been the same critical acclaim for the SCT. I just wrote plug in tuners off as a placebo effect to most people...

Im not sure how much the Hemifever tunes translate to the Durango?
And keep in mind manufaturers will do as much as they can to deny warranty claims. A tuner can be an easy excuse. They can tell even if returned to sock form. Unlikely but its a possibility.

I cant say for sure that they dont offer some results, I just didnt get any and even if they do, Im not sure how much bang for the buck returns youll get or if its worth it.
My two cents.
Good luck!

 

I have a Hemifever tune and love it. I have had other rides tuned by other tuners so I know a good tune. I did get a couple miles per gallon increase and IMO it came from the car staying in MDS longer due to the increase in TQ.

Now as far as the warranty issue the Maggnison Moss act prohibits a dealer from voiding your warranty (google it). They have to prove in a court of law that your "mod" caused the problem and it only voids that part. As far as them tracking the tune. Yes they can but it requires them to first have a suspicion and second get permission to search for the tune and then have technician that know how to do it. Not all know how to do that.

As far as the sound your might hear a little bit of a "growl" but most likely that is from you getting on the throttle more. Unless you change your intake and exhaust your probably not going to hear a difference.

I have heard good things about SCT but never used them. Stay away from Hypertech. They are crap (been there done that). I have had nothing but good luck with Diablo.

Hope this helps. Enjoy!

 

Be carefull with Maggnison Moss. All they have to do is state that the aftermatket over ride of their computer caused the problem. When you modify an OEM computer tune... That aint hard to uh-hum "prove" that youd run your engine outside of OEM specs if they really wanted to.
Its not as simple as fighting a denied claim because they are saying your carbon fiber hood or Eibach suspension caused an engine failure. Those kind of BS denials are what the Act has teeth for.
Just be careful about being too overconfident in Maggnison Moss when you start going ballz deep in to engine performance mods. FCA has lawyers too.
Again, its unlikely they mess with you over a tuner, because they dont mess around with piddly warranty issues, but its a possibility if the problem warrants a look see, and if its serious enough they'll look. Those are the kinds of issues I was talking about when they look for reasons to deny a warranty.

I know a guy that drove his truck through a mud puddle, he sucked water in and locked it. Even though it was an obvious design defect, they took the stance of user error right off the bat and denied the claim and it took some doing to get it resolved.

 

Agreed it doesn't give you free rein but it does give the buyer some help if needed. Most don't know about it. I knew when I cracked into the motor that it wasn't getting fixed under warranty but that doesn't make the electric seat go bad either. That should still be fixed under warranty. What caused a bunch of dealers to start voiding warranties was the big surge in diesel performance and boosted cars like the WRX and Evolution IMO. We have really seen a huge increase in performance products in the past 10-15 years.

 

Well, the Magnuson–Moss Warranty Act was enacted in the mid 70s...well before diesel performance and WRXs came out. I dont think its intended purpose is what you think it is and you may be misinformed. Its really a bit of a reach. I certainly would NOT try to hang my hat on the Magnuson-Moss Warranty act.....
Best bet, be prudent in your engine mods untill your warranty is up or just say F the warranty and go nuts.

No one and no thing is going to protect your warranty if it is deemed that your tampering with OEM engine operation specs caused the problem. Like I said, it protects you from them claiming your super rad new spoiler did not cause the coil pack from burning up and SURE, it also protects you from them claiming your Diablo 93 octane tune didnt cause you power seat from crapping the bed. Among insuring other fair and above board warranty policies.

That is not what you implied in your previous post...cracking the motor is not much different than changing the fuel mapping, timing, advance, shift points, boost and numerous other engine peformance parameters in your computer.

There is no magic bullet of protection.
