GIAC G.I.A.C. 997.2TT 3.8L DFI Performance Software

G.I.A.C. sets the industry standard once again with the release of their Performance Software for the 997.2TT.

With gains of +58 crank hp and +40 crank tq, perfect daily driving manners, a silky smooth powerband and the ability to switch programs on the fly, this is the only software worthy of your Porsche.

In addition to the standard dyno testing, we wanted to give you another way to measure the benefits of G.I.A.C. Software. With that we took our in-house 997.2TT to the track for some closed course acceleration runs. Our Acceleration Comparison gives you a visual and statistical representation of how a stock car compares to one with G.I.A.C. Software.
Extensive dyno and street testing has resulted in a performance chip program that dramatically changes the power profile of the 997.2TT. Critical parameters such as cylinder knock activity, EGTs (Exhaust Gas Temperatures), and air/fuel mixtures were monitored under a multitude of engine load and ambient weather conditions. This performance chip program retains all factory safeguards to ensure reliability even in the most adverse situations.

G.I.A.C.s programming just became an even better value. Purchase the Pump Fuel Performance program and receive a free Handheld Flashloader and Stock Power program.

Why G.I.A.C.?

G.I.A.C. is a software engineering company with two decades of experience tuning cars. They are known for creating "factory smooth" performance software with exceptional power and reliability.

Their software replaces the standard software in your car's engine control unit. It is programmed to adjust ignition timing, fuel delivery, fuel metering, boost settings, rev limiters, and/or speed limiters to optimize performance and, in some applications, fuel economy.

Performance-tuned programs are designed to dramatically increase torque and HP without sacrificing smooth drivability. Many programs are also created to accommodate numerous after market performance modifications.

Who is G.I.A.C.?

G.I.A.C. is focused on designing after-market software for Porsche. G.I.A.C. is also behind unique Flashloader Software and handheld switchers, which enable remote controlled chip switching for easy switching between multiple G.I.A.C. programs and the stock program.
