I'm old. I never used youtube back then lol. I forget where I saw it. Just odd the way it still says 410 including extra 130. That makes it sound like total. It should sand and an extra130.

I originally thought it was always 130 above at all times too, wouldn't turn that down!

I haven't towed with an ET. I'm sure you can feel the extra 130 lb/ft off the line but it disappears almost immediately. I could be wrong on the exact number but IIRC it's like 1500 rpms and ET is done. So it's not really doing much.

That little bit while it's active is very noticeable....objects in motion and all that. I can't tell the difference when unloaded, and I'm sure it makes almost no difference in 0-60 times. It's just a bit of pep coming from a stop with a 6000lb trailer.

For sure. That's what made me get my first etorque, before I found out otherwise. Funny story, I totaled my last Ram. I had been leasing since my last purchase on 2009. Leasing used to be cheap. When I went to get another, there were no lease deals, and the replacement truck would have been $300 a month higher payment. I couldn't afford that. I tow a 4,000 boat. What could I do? I ended up leasing a 21 Durango R/T with tow package. I had to act fast because there were only 3 Durangos in Michigan with tow packages. I had injured my right knee in the accident, so I couldn't even drive, and had my son in law go to drive it home for me. Found out in a couple days the hospital missed my damage that needed surgery. I couldn't even drive my new car for over 2 months. It was probably another 2 months before I realized it wasn't shutting off at lights. I had never even noticed I didn't have etorque.

It is a little bit misleading when they say, "including an additional 130 ft-lb of supplemental launch torque enabled by the eTorque system". The 130 ft-lb of torque is not included in the Hemi torque specs, so they should have worded the statement to say, "plus an additional 130 ft-lb in the first 1/2 tire rotation"

Found the video back:

The problem with YouTube is any knucklehead can produce a video and make statements that aren't true. The eTorque system provides supplemental assistance during the first 1/2 tire rotation and has nothing to do with speed or RPM's.

You just regurgitated what automakers have been telling us for years.

My entire point is that in the real world this is not the case. As a "car wh0re" who has owned and reviewed dozens of vehicles over the last few decades I can tell you that in the real world, DI doesn't produce any of those claimed benefits, but it does produce those claimed problems.

As somebody already mentioned, the fact that Ford added port injection to their DI 5.0L engine and then developed a new 7.3L engine with NO DI at all is testament to the fact that the assumed benefit of DI doesn't counter-balance the drawbacks.

I can only speak to my personal experiences with GDI engines, which I’ve had two. 2006 Mazdaspeed 6 which I drove for 70k miles and traded for my 2012 Audi S4 which I still own and daily drive. It has 75k miles. As far as I know both are GDI only. I’ve never had an issue. I use top tier fuel at 93 octane and I run an injector cleaner every 4-5k miles. Which I also do on my 6.7 Cummins. Never an issue. Just my .02. I’m about to have this Hurricane motor so hopefully I’m not making a huge mistake. Time will tell!
