Jeep Eco Diesel w/ GDE Tune or 2016 Explorer Sport Eco Boost with Livernois Tune

Hi guys,

I've enjoyed prowling in the background of these threads for a long time and have received a lot of great information, thank you for that.

In the next 6 months I will be buying a used vehicle, I have had my eye keenly fixated on the 2015 Grand Cherokee Eco Diesel with the GDE tune for some extra giddie-up. That was until one of my buddies who works at a Ford dealership told me to just look into the 2016 Explorer Sport with the Eco Boost + Livernois tune. Here's what I found. Just looking to start conversation, get input and opinions with some side by side comparisons.


2015 Jeep Grand Cherokee Eco Diesel
Manufacturer declared: 240HP / 420ftlb
Stock dyno: 220HP / 365ftlb
Tuned: 248HP / 428ftlb
*I did recognize the dyno tests on a stock EcoDiesel came out lower that Manu advertised : Green Diesel Engineering -

Tuned Gas Mileage (Approximately) : 24/32 - Mixed 28. So 50k mi of mixed driving with diesel at $1.99/gal = $3,554.

Tune Cost = $695, with no handheld tuner included

Tuned 0-60mph time =
?
Tuned 1/4mi time = ?
Curb Weight: 4800lbs
Towing: 7200lbs

I really like the Jeep's Interior and exterior looks & fuel range it can have(6hr drive to the cabin). The offroad capability is a plus, but I dont offroad in sever situations enough to buy solely on that reason, but like the capability. Torque numbers are great, towing is more than enough. I love the Jeep community. My hesitation is space & reliability(this truck is low in most reliability comparisons). The diesel emission system seems unproven and prone to problems.


2016 Ford Explorer Sport Eco Boost
Manufacturer declared: 365HP / 350ftlb - (yes, I know comparing to diesel is apples/oranges)
Stock dyno: : 275HP / 290ftlb
Tuned: 334HP / 372ftlb
*I did recognize the dyno tests on a stock Eco came out lower than Manu advertised : Livernois Motorsports

Tuned Gas Mileage (Approximately) : 18/24 - Mixed 20. So 50k mi of mixed driving with 93 octane at $2.45/gal = $6,125.

Tune Cost = $600, with handheld tuner included, new 3 bar map sensor needed ($50) + 93 octane.

Tuned 0-60mph time =
Sub 6
Tuned 1/4mi time = 12.81@107 recorded in 2013 with intake & exhaust mods
Curb Weight: 4900lbs
Towing: 5000lbs


The Sport seems to have good reliability ratings all around. I am going to give it a hard look. I know the Sport is built on the Taurus frame and doesnt have an ounce of the offroad capability of the Jeep. My day to day driving is on paved roads. The only offroading I do is up north on sand/dirt fire roads which rarely get too hairy. I do live in WI so I have to deal with a lot of snow, sleet and rain which both vehicles can handle.

I think both diesel and twin turbo engines have a future in the USA. Too bad it takes so long to follow Europe's lead on that. Ford is going all in on these Twin Turbos while Chrysler/Jeep seems to be just trying to stay relevant with their engines.

What do you think about the comparison? I know there are some Ford haters out there

If performance is what you are after, just either tune or supercharge a Hemi.

I'm not interested in spending $9000 to get 15mpg, I might as well buy a SRT. These two options are as close to a plug and play performance SUV as you can get for under $45k.

Are you guys generally happy wi your turbo diesels? Do you plan on putting 150k miles or more on them or will you bail before then?

Re: Jeep Eco Diesel w/ GDE Tune or 2016 Explorer Sport Eco Boost with Livernois Tune

It seems like I saw somewhere that the GDE tuner puts the Jeep at 7.2 seconds for the 0-60MPH, which is about 0.5 seconds faster than stock.

The explorer has the edge on performance.

If 0-60MPH is your typical joy, then the explorer would be the choice. 0-30MPH, however, I'd be willing to say that the Jeep has the edge because of the torque and gearing. For me, I care more about the 0-30MPH time since that really seems to be where the "pulling away from danger" events seem to happen.

I drove the 2014 Explorer (a little different than the 2016, but still a car chassis) and it felt closed in versus the Jeep. It just didn't have the headroom. The windows felt a little short as well. Maybe they fixed that in the 2016, but it stood out in our test drive.

Cabin comfort (including noise levels at highway cruising speeds) is a big part of where the Jeep shines. The other areas where the Jeep shine are range and off-road capability.

Since this is purely a subjective decision, you really should test drive both stock and choose based on that. Just know that the tuner is going to make each a little peppier. Paper spec comparisons only get you so far.

Personally, I plan to keep my Jeep until the average repair costs exceed the payment on a new vehicle. For a lot of vehicles, that's between 8 and 20 years. I put about 10K miles a year (and rising) on our Jeep, so that's 80K to 200K miles or maybe more if we take some longer trips in the years to come. It's anyone's guess how this will play out for the diesel Grand Cherokee.

Re: Jeep Eco Diesel w/ GDE Tune or 2016 Explorer Sport Eco Boost with Livernois Tune

Plan on putting 100K plus miles on my Jeep diesel. Performance wise very happy in stock form. Pulls hard, tows over 7400 pounds, plus my daily commute 70 miles, getting 31 mpg. Will be adding tune just because love performance upgrades.
For performance thrill, drive my corvettes

Re: Jeep Eco Diesel w/ GDE Tune or 2016 Explorer Sport Eco Boost with Livernois Tune

I can't see a tuned explorer running 107 trap speeds. Tune, CAI, exhaust= 107mph on a 5k lb vehicle with "only" 334 HP?
It seems off to me.

Now maybe with a bigger turbo, different cylinder head mods then absolutely. But I'd suspect you'd be putting down 400 to the wheels.

Re: Jeep Eco Diesel w/ GDE Tune or 2016 Explorer Sport Eco Boost with Livernois Tune

The roughly $3000 in fuel savings with the eco diesel is a nice feather in the cap from our point of view.

Torque you can feel, horsepower you can see. From the driver's seat, I prefer the feel of torque in city driving, in most day to day driving situations one just can't use peak horsepower without risking a ticket.

All really good input, thanks guys. This is going to be a tough decision. We'll see how the test drives go, maybe I will prefer one head and shoulders above the rest.

Re: Jeep Eco Diesel w/ GDE Tune or 2016 Explorer Sport Eco Boost with Livernois Tune

Been there done that. When I test drove a bunch of SUVs none compared to the Jeep. The impression the Jeep gives me does everything I wanted it to. However there are many great rides out there these days.
I don't know of anything that can knock down the mileage I get consistently except the Jeep diesel. I can get 30-32 mpg all day long driving 65-70 my average is about 28.5 mpg over 37,000 miles.
But it isn't the mpg it is the entire package with air ride, FCW, ACC blind spot and cross path that made the difference.

One thing I don't like is the huge bling spot on the A pillars and C pillars that the Jeep has.

Have a 13 Subaru Outback which has virtually no blind spots and is a very nice ride too with FCW, ACC. But it is more of a car height ride and does a great job.

Toyota Highlander as well as the Explorer and many others are great choices too...

Re: Jeep Eco Diesel w/ GDE Tune or 2016 Explorer Sport Eco Boost with Livernois Tune

the ecoboost rips, that's for sure... I prefer my ecodiesel w/ tune though. I think all n' all, the jeep is just a better driving and refined vehicle; its got that unmistakable euro feel. with the other mods I have coming I think this eco will be every bit as quick, fast as the ecoboost. plus I get over 30mpg on the highway going 75mph +!

Re: Jeep Eco Diesel w/ GDE Tune or 2016 Explorer Sport Eco Boost with Livernois Tune

If its all about power and 1/4 mile a low mile Jeep SRT would be the way to go.

One of the larger selling points to me is the Uconnect 8.4; it kills mylink and Sync in terms of user ability, bluetooth connection, GPS, scrolling through Sirrus . Infact I don't think I would want another vehicle that didn't have Uconnect 8.4. I've had quite a few rental cars in the last year (always National) the only "infotainment system" that came close was Hyundai's. Now I just wait for an FCA vehicle at the rental lot, so I've had Durango and a Cherokee for the last trip.

Also consider a euro version Maserati Diesel (ghibli or quattroporte) uses the same drivetrain (Engine and ZF 8HP70 Transmission), even the Maserati Levante SUV will have the same diesel powertrain into 2019. BMW X5 and Rolls Royce Phantom both share the same ZF Transmission. That makes the EcoD and the 8 speed ZF a value buy IMO.

Re: Jeep Eco Diesel w/ GDE Tune or 2016 Explorer Sport Eco Boost with Livernois Tune

Love my JGC. Looking forward to the tune enhancement.
The only thing that irritates me (besides the absurd shifter) is the turbo lag. I am hoping the tune helps a bit with that.
