Let me suggest that you don't waste time or money on flashing your TCU or modifying the torque converter either. I've been down this path. Its not fun. The tip tranny is a weak link.
When I had the Fabspeed ECU reprogrammed, to go along with headers/cats/muffler change (and more) they also did the TCU. By the way the Tip S transmission is the same (except Porsche is 4 wheel drive) as the MB AMG 65 and that has far more torque and power than the 996 TT.
Does the 997 use a different tip tranny? Or is it the ecu that is more advanced/tunable? I'm new to tips, and I'm enjoying mine, although I do want to make big power one day while staying tip.

There is actually a stand alone TCU that can be adapted to these cars. It's called PCS (powertrain control solutions) and the model of the tcu is TCM-2000. According to Russell, it's pretty much plug'n'play, except for the fact that it requires an output shaft speed sensor to be installed, as the factory wheel sensor signals can't be used as inputs.
I've checked it out and looks promising, and the price is amazing, so even with extra cost to fabbing up a sensor ring/speed sensor setup on one of the output shafts, should be relatively inexpensive. All other factory sensors/actuators work with the unit.
The other thing that would have to be done is recode the ecu to think it's manual, so it doesn't look for the tcu signals.

Would you be willing to share your research? At what torque level does the 996 tip become unreliable? If it is indeed the same trans as the S65, I ran mine reliably at 850 ft-lbs for 60k miles. Do we know for sure whether or not it is the same transmission? Or, is it a RPM limit thing? Are you saying "you can't make big power" because you can't raise the full throttle shift RPM?

Guess I should have looked around some more. This one gets you to 7000 rpm.:
I too have been on this for a while. The place I listed above says they can handle 1000 hp after there upgrade. I do not know what torque That is at. The 722.6 nag1 is in many chrisler cars and they ruteenly upgrade for drag and hotrods. They only do upgrades and then run on a dino. The price is reasonable. I have my 2 spairs going to them . And should be back on line in the spring.
We offer transmission tuning for all Porsche non-stick cars.
Our TCU (tramsmission control unit) tune will increase the shift speed, it will reduce the time from a manual gear change input to the time the actual gear change occurs, and most importantly it will adjust your torque maps so that more torque is allowed to the wheels.
You will notice tons of gain in the mid-range, for example on a Gallardo we did last week we took it from 91 Ft-Lbs at 3000 RPMs to 166 Ft-Lbs at 3000RPM.
Shoot me an email at wlw@rsctuning.com and we can discuss it further if you would like.
is this tuning as good as the tuning you provided for your Aston supercharger kit???
This is were I have 2 tips headed for. For what they do and for the price it puts it in my comfort zone.
Would you be willing to PM me the details on your builds? I have a transmission heading to FL to get rebuilt and they say it's good for 1000hp (I'm only at 600) and would like to compare what were getting for the money. I went to the site link you provided and looks like they do alot of domestics.

BHT
Can you eloborate further? On weakness- at what power? Why is modifying the torque not good or is it just not worth ther extra money as I've always had the most bang for the buck with automatics using a modified torque converter to get the stall in the power range.
Maybe it was because the tuner was there in person and tune both TCU and ECU (retuned) at the same time.
