I've had all three actually. Still have my 20 Limited with Etorque, will be sold when it comes out of the body shop
Had a 25 Laramie SO for a month and now have a Tungsten with the HO.
The SO and the HO are night and day hands down better than the 5.7 HEMI and I'd argue better than the 6.4 SRT car engine. The 6.4 car engine would need a different cam and intake in the truck, otherwise it'd have to be wound up too high to make enough torque to move a truck weighing 2000 more pounds than the car it was designed for.
The SO had a 3.55 rear and got about 18 mpg hand calc'd on the same route my 5.7/3.21 truck would get 17-17.5. The SO has power everywhere in the RPM range and you do not wait for the engine to rev up for power, it made for a far better driving truck than the 5.7.
The Laramie also had 20's and the standard coil spring suspension, it rode good but it was no comparison to my Limited with air ride; people that say they ride similar are a damn lie or they've never driven an air ride truck.
The Tungsten with the HO is far, far superior to the 5.7 and power wise better than the SO. I do think the SO drives a little better than the HO but that may have also been the 3.55 vs the HO's 3.92. The SO seemed to drive better at part throttle or it felt like it had more power at mid throttle than the HO. The SO has 10.4:1 compression whereas the HP has 9.5:1 compression , almost a full a point higher and that may also contribute to the SO feeling stronger in the low end and mid range when staying out of boost. Neither engine appear to have much lag and the HO is definitely the bigger monster once you command boost and pulls all the way to ~6200 rpm and just keeps pulling with each upshift, never rolls over or stops accelerating right up to the speed limiter.
My Tungsten gets about between 1-1.25 less MPG than my Limited and about 1.5 less than the Laramie SO I had but it also has a deeper rear gear than the SO. I expected less MPG than my Limited simply because of an additional 150 HP and 110 lb ft of torque much ;ess the different gear. gas only has so much power per BTU and to make more power, you must add more fuel so those looking/thinking/arguing that it should get better mileage because its a I6 simply don't understand engines and fuel
I'm not concerned with the Hurricanes "complexity" at all and I don't really feel its complex and more complex than the 48V HEMI etorque system. Twin Turbo I6's have been around for a long long time, thus far, my HO has not disappointed.
The only real issues with the 25/26 really has nothing to do with the powertrain but the new Atlantis electronic canbus architecture. I've had no issues but I've seen in FB groups that p[eop[le that bought the 5.7 in a 26 are having the same electrical issues some 25's trucks have experienced. I personally think UC5 sucks rocks and that UC 4 is better and much faster but there's no getting around that.
Both the SO and the HO are stupid silky smooth, so much so that I have to look at the tach to see if its even running. The I6 engine sound exhaust is really the only thing i'd complain about but even that I got over very very quickly, the only time you can really hear the I6 exhaust is when your in a HEMI truck trying to keep up.
There is no way I'd buy the HEMI over the Hurricane, NO WAY, even if the HEMI was cheaper.
I still like my 5.7 Limited and if it was hit by a light running no driving indian, Id probably still be driving it now but it's no comparison to the Tungsten. The SO/HO trucks seem to handle a little better as well, likely because there's less weight over the nose. The Tungstens air ride is also much faster than my 20; raising and lowering the truck is a lot faster in the 25.
Oh yeah, using sport mode turns off traction control and puts the truck in 4Hi, stall it out to 3600-4000 rpm and hang on; this thing moves out. Theres people 60ft'ing 1.7-1.8 sec and running high 12's stock and 11:90s with a JB4 or a CAT 6
