Re: WK2 Performance

the tuners will come......just give it some time. It took diablo and superchips several years if i remember correctly for the WK. Superchips I know for sure knows the market is there and is busting their humps to get a tuner out there.

Re: WK2 Performance

I think the motor for the most potential is the CRD, as it has a variable vane turbo and can deliver more significant power gains using its stock running gear.
I will be watching the euro tuning markets, as this will be the powerplant of choice for euro models.

I tend to agree. Had the CRD been available I'd have that instead of the Hemi since the prime purpose for my WK2 is pulling a 5000 lb trailer (aside from normal around town work).

While the off the line performance of the Hemi seems to be lacking, mostly due to torque limiting and gearing IMHO, once you're moving it's quite responsive, much more so than the V6. When you double the vehicle's weight, like I do when towing my trailer, the motor really shines. With it set to tow/haul and the proper gear selected (3 or 4 depending on grade) you can maintain legal highway speed on any interstate grade without really breaking a sweat. I know because I did on my last trip running multiple 5% - 6% grades, the maximum standard for US highways, the WK2 Hemi performed flawlessly. In fact, I hooked up with a guy pulling a similar trailer behind an F-150 with the 4.6L modular motor and I walked away from him on every grade.

When I trade the Overland for an SRT8 in a few years it will all become a non-issue

Re: WK2 Performance

Here is the clincher that the Hemi is a not living up to its full potential.

Take a 2005 Cadillac Escalade which weighs more than the WK2 Hemi and has less Power but can out accelerate it anywhere at anytime- and it is doing it with 50 less hp and 10 less pound feet of torque.

When the 2005 Caddy first came out people raved about its power- not so with the new Hemi.

Both new Jeep Motors feel the same- Lethargic, which is very surprising despite the Horsepower and torque ratings???

The V6 is a dog, it can get out of its own way but it does not have brisk accelaration like a near 300hp engine should.

Very disappointed- hope they can work it out in the model years to come.

I agree with the above poster; my reflash did nothing and might have even made things worse- not to mention I had to twist the dealers arm to get him to re-flash it.

Hopefully a tuner can wake up the Hemi.

Re: WK2 Performance

Sorry to dig up an older thread, but a neighbor with the Q7 (who just ordered a WK2 Hemi) found this video of a WK2 Hemi running 0-60. It isn't that great but does appear to have the Tow/Haul engaged and is about 7sec elapsed time, give or take a tenth, FWIW.
