I’ve owned a 2500 CTD 4x4…’05. It was a 610 version, if I recall correctly.
And no, this I6 TT feels and sounds completely different. If you’ve ever driven a Honda Accord with VTEC, but a V6…that’s a closer comparison in sound & feel. And no, I’m not joking.
That being said, the I6 TT is vibration-free & loves to run from 3500 RPM to its 5750 redline. But, it’s not really peaky, just a bit sluggish off idle until 2300-2400 RPM, when the turbos start building usable boost & torque.
Best of all worlds to me would be the latest V8 Duramax in an RHO chassis. But, I’m a diesel fan, so we are a minority in the current age.
