We recently had the chance to tune this Porsche 996TT Tiptronic with Tial A28 turbos.  The car was also equipped with a full Agency Power exhaust system, Agency Power YPipe, Agency Power Intercoolers, and Agency Power TB/Plenum.  It was also running a Greddy EBC and 60lb injectors.

With the car strapped down to our Mustang AWD Dyno, it had a full tank of 93octane and a base file. We ran the car out and datalogged it.  After 3 different datalogs we made 1 revision to the file and got More power! We wanted to increase midrange and top end power as to much torque on the tip would make it slip. So going through all the tables for that RPM range, we created the final map. We ran the car out and got 532awhp and 563ft/lbs of torque. But we were not done. Softronic tunes all files to adjust for higher octane. So with only 88miles left in the tank, we dumped in a 5 gallon drum of VP MS109 octane. Cranked up the boost to run 1.6bar and we got some good additional gains. The cars top numbers were 571awhp and 632ft/lbs of torque. On a tip, this is really the max as we could feel the tranny did not want to stay together with that much torque. By Mustang standards this is over 700hp and 750ft/lbs at the crank.
