Eurocharged TCM Tune?
I have to admit, i bought the TCU tune a year ago and still have not ordered them to ship it out, as i actually would want to wait until all the other mods are installed so they can adjust the TCU to my Torque settings (i hope i understand that right that the torque limiter and management is done by TCU?).
Anyway can you tell me how much improvement in drivability that smaller upper and tune brought to you? How much quicker does it feel?

TCM should be delivered today around noon so going to dip out of work early and hopefully I'll be please with the results when it's installed again.

So the things I noticed. I pulled away from the stop leaving my neighborhood and it broke traction at 20% throttle. Not that that's any accomplishment in our cars but the change was that ESP didn't go crazy and bring the hammer down on me.
The shifts are much quicker and the buttons are much more responsive. Now don't get confused. This tune did not turn the 722.6 5spd into a DCT trans by any means but it does react much faster. While just cruising I was playing with the buttons and between button push and trans shift, it was less than a full second. To me that's a big improvement over stock considering the wait before would almost put you to sleep.
Also a nice change is that comfort mode seems usable at any gear now. Even before downshifting in "C" if you give it gas the car moves forward as though it's a manual car in a higher gear. No hesitation or car wondering. "Does he want to use the Torque on tap?" it goes, and is smooth about it. Also I have a FSP so this may have something to do with it as well.
Downshifting is much quicker than before, I kicked it down going under a bridge just to see how quickly it would, and as soon as I felt the click it shifted and threw me back before I had a chance to let off of it. Nice considering some runs I had with lesser cars were closer than they should have been because of the kickdown delay.
Finally, the pedal travel. It doesn't seem to need nearly as much gas to get the car going. I found myself having to readjust my foot because a little bit of throttle goes a long way now. Before you could really step on it and the trans wouldn't shift until your foot was nearly touching the floor. Wish I could properly explain the rest of it and it may be the torque converter lock up but it feels like the transmission and engine are a team again. Rolls smooth at all speeds, until you get on it.
Sorry if this sounds like gibberish to the more experienced users but these are just my take aways for the 20 minute drive back in DC. And considering I got a deal on it. I'm very happy with the results. Oh and bonus, finally saw 17 mpg on the way back in. Nice change.
FWIW I kept the old (wrong) sensor and if I ever have to let someone else drive the car (like a shop) I plan to swap it out with the right one, instant loss of at least 2-300HP/TQ yet the car runs fine and doesn't throw any DTC's.
The torque is constant, especially with ESP off but once again that may be due to my Fixed Pulley. As stated, there's no night and day difference but it makes the car feel just so much more athletic, responsive and urgent.
Seriously suggest it if you are on the fence. It's a nice benefit and there's the ability to have it retuned for transmission mods as well.
