From the FACT that they cracked the ECU two years ago before anyone else did. From the FACT that the only other tuner to crack the ECU is COBB and they just now released the access port. From the FACT that the GIAC product is so good that dealerships offer the tune as an add-on.

so, in other words, you made it up.
Lets be clear, they may be great on the 991TT platform and if you had said that they are the most prolific 991TT tuner out there, I might even agree. As you know, however, there are many other Porsche platforms out there and I'd say there are many other tuners with a similar or larger impact on the Porsche tuning community.

Back it up, then. Show me the tuners that consistently beat GIAC to market and then occupy a larger market share. And stay on topic, I'm asking about tuners that have cracked the ECU encryption and written files to it. Not piggybacks and mufflers.

Cobb has had 996/997 tuning for a long time. They only now brought the 991 tuning out, but they're also the ONLY ones with an accessport type product, which means no having to send my ECU out, or seeing a dealer to flash it. Updates would be a snap as well.
They seem to have a decent rep with the 996/997 tuning. I believe the tuning is open as well - so if you know something about tuning, you could tune it. I wouldn't because I know only enough to be dangerous -
I few months ago I installed the Fabspeed piggyback on my car and had some noticeable gains but also some areas of the powerband that just weren't working right. AMS Performance is nearby and I know them very well from work on my GTR and they were able to get me the new Cobb Accesport so I pulled the Fabspeed piggyback and just loaded a off the shelf map and the difference is amazing. In 2-3 weeks Cobb will release whatever is needed to do a full custom dyno tune and it should lead to even more gains. My car bone stock with just the Cobb made over 550whp on a dynojet. Eric Gaudi at AMS handled everything and is great to work with. They are also in the process of designing intercoolers for the car. I will attach my dyno sheet. I expect to pick up 10-15 more wheel horsepower when they custom tune it.
Something screwy with that sheet...and we can't see HP>RPM, only to speed. Why does it end at 60MPH?
They didn't use the right sheet for the printout. The bottom line is that the car is vastly improved after the Cobb tune except for one area (see picture below) that AMS will fix when they custom dyno tune it. And the horsepower figures are accurate. I don't know why they used the wrong sheet but I suggest you call Eric Gaudi over there and ask him any questions you might have. The car has made a noticeable jump in performance with zero sacrifice of driveability

There is no torque as they did not use an RPM pick up so they just go off roll speed.
Great back to back comparison!
And to be clear this is a full ecu rewrite. No piggy backs, no gimmicks. We have full control over the ECU including high and low pressure fuel, ignition timing, cam timing, boost control etc.
There are lots of results coming out more and more of the tunes. With the AP we were able to win the Pikes Peak Hillclimb on just an exhaust and flash in our class. In fact in our class the 991 took 1st and a 997.2 Turbo with an AP took second.
