I bought my TechGT kit from them a while back, they know Electromotive very well and have custom trigger mounts, crank wheel and cam wheel solutions for the 944.

Hardware is EZ The Trick is to have a Dyno tuner who knows what the hell they are doing. My Current System Hardware-wise has never let me down. They Tuning on the other hand... I took the car to an awesome tuner this spring and After 4 events and different tracks it never missed a beat, but BEFORE finding a tuner I blew up 2x in 2 events... I Am running clewitt hardware and Electromotive stuff....

The have ecus, injectors and induction systems.
And yes, I agree, more people should be looking at DTA.
Their ECUs (all of their products actually) are top quality and have massive list of features.
I was just send the new flash add-on upgrade,
- Throttle blip on downshift based on the potentiometer position
- Ignition cut on downshift when using paddle shift (sometimes called gearbox relax)

I'm not affiliated, other than owning the product (previous gen E48) and being a friend of Wayne@TPG.
Max (Energy) and I were just talking about this a couple days ago and an equivalent system (in DTA) to duplicate what he wanted from EM was way way less $$.
From their site, this is the posted list of features for the TEC gt list $1799.00 - reduced $1499.00

I hate to be that guy but as a contrarian... look at MS3Pro. It has all those features too. If you don't need all of that you can get a MS3 for well under $1000 with 90% of that functionality. I'm biased because I have MS2 (Microsquirt) in my NA and MS3Pro for my 951. There's also something blowing in the wind about a plug and play MS coming soon

Yup, had to send the ECU in to Electromotive because Some Hardware had to be updated, its Like a Tec 4 now. RPR Did an Awesome Job Tuning it, it wasnt my hardware at all last year that was giving me fits... I was REALLY detailed with the honing a ring fitting Ect... The Engine is Smooth we Even got rid of the ISV, and went back to Batch Firing instead of sequential... It starts Cold and Idles Perfect..... I actually like it so much I want to build a Stroker and Go Right to the GT class and skip "Stock Stuff"

Take a word of advice though, unless you have an able budget equal to the amount of all the rest of your current every day life expenditures to throw at hobby racing with no monetary prize recoup, then you'd be wise to stay in one of the SPEC classes.
In GT, other than the rare (I would say totally non existent if not for 1 guy I know) racer with just mad skills, these guys have a crew of 3-5 mechanics, 3 sticker sets of tires already mounted on three sets of wheels, a used and brand new set of rains and a motor coach/toter where the driver chills in between sessions....
I almost went the route you are contemplating, so far to the point that I actually built the car, 2400lb 944T, 450 hp, ECU, TC, shift cut, etc, etc, etc,
Saw the error and backed up and punted.
Built 2 SP2 cars.
Moving to SP3.
Stay there, sit tight, CR is going to do something to balance the 944T.
I have no interest in speeding up 944T but for the good of the class, since they asked for proposals for a solution, I have a friend working on a max boost hardware solution that PCA can plug into and monitor.
If the buy in is reasonable, I'll fwd it to Fricke to consider.
Secondly, look at the fields, SP3 is where it's at if you want to go faster than SP1.
There aren't enough SP2 cars, at least in the SE, that's why we are changing class.
You won't have anybody to race with in GT in a 944.
Been there done that too.
Helped a buddy convert his SP2 to GT with 968 engine.
He was only one in class 90% of the tracks we went to (I would travel as wrench).

BTW, " Go Right to the GT class and skip "Stock Stuff" "
EM Tech3 ECU already takes you out of "stock stuff".
Bosch Motronic stock DME and KLR are all that's allowed currently + any spark delivery coil that retains cap and rotor.
