Has anyone here trashed a stock torque converter after a Max Torque Eco Tune Install?

I know GDE doesn't recommend the use of the stock converter with that tune, but.....if so, how long did the converter last before it went kaput?

I've been considering the tune, but have the stock converter, which isn't troublesome...yet anyway. I'm not towing anything significant, but another boat is in future plans, so that may change.

Yeah I got the eco-full torque with the stock TC for about a month now. I am actually trying to get the TC to start to fail so I can get it replaced under warranty but no-go yet. I've felt a couple weird jerks here and there but I haven't experienced anything like the shudder people have explained here. I actually got the TCM tune also, maybe that is delaying the failure of the TC, I don't know. Three trips up the mountain to snowboard and some aggressive city driving but no real problems yet.

I have the Hot Tune.............I drove with the stock TC for 3000 miles or so before I put the transgo shift kit and the Sun Coast TC.........It wasn't destroyed when I changed it but could feel the shudder any time I wanted to.......HJ

I can't answer your question but will share my experience.
My TC was replaced under my extended warranty. I had the regular Eco tune and F37 TCM and at 32k miles with about 7k miles of that towing a 3000-3500# travel trailer with the constant shifting up and down going over some mountains. I found the standard ECO tune that gave good preformance gains when not towing was of little help while towing so I don't think it mattered one way or the other as far as the original TC failing. When the TC was replaced they found TC clutch material in the pan :|
With the "Euro" Chrysler TC I updated to the "full torque" eco tune along with a pre f37 tcm. This thing now has the low end thumping power that I'm sure would shread a stock TC. :wink:
My first full tank with the above configuration showed a mpg increase of 3 mpg on my typical all city short trip driving from 20 to 23 with winter fuel :shock:
I am really pleased with the original shifting patterns all of our CRD's originally had combines with the full torque tune :jester:
So after four and a half years of ownership it now drives like the Jeep I originally bought :JEEPIN:

The GDE tcm tune may be helping to avoid disaster by keeping the TC locked longer.
