Why do you want to remove it? They advertise them as the next best thing to sex
I have an e-Torque in my RAM (not planning to remove it by the way).
Some pros of the system are that the start stop system works well. I seriously HATE every start stop system I have ever driven; they suck. But this one doesn't, because it uses the "alternator" to start the truck back up. Since it is starting it via the crank and the truck is in gear, it moves the truck forward slightly as you are starting. There is essentially no difference than a regular automatic when driving it.
It seems to me that mileage improvements of the system are minimal. Of course, I haven't tested any truck that is similarly equipped to mine without the e-Torque, so I have no comparison. But the mileage on my truck certainly isn't great, and I'm not sure I get a 1 MPG improvement that the e-Torque is supposed to provide. But maybe I do?
I love my truck and I would probably equip it similarly if I bought it again, perhaps except
for the e-Torque. The jury is out if it is worth it. If it truly gives me 1MPG better mileage then it is worth it. But if not, then it is expensive for very little added benefit.
