The return to round headlights, a dramatically improved interior, and greatly improved handling are just a few of the reasons the 997 generation of the 911 is so widely loved. While those are certainly good reasons, we love it for the same reason we love most cars, performance! Whether it's equipped with 3.8 liter S trim or the standard 3.6 liter engine, both variants of the 997 offer enthusiasts amazing potential for upgrades including everything from cosmetic upgrades to engine performance. Once we start taking about engine performance, we have to mention GIAC. If you're driving a 997 or 997S without GIAC software installed, you're leaving unused horsepower on the table, along with increased overall engine performance.
GIAC Porsche 997 Performance Software:
Horsepower gains: 10-20*
Torque gains: 10-15*
*To get the full benefit of adding performance software to your 997, we highly recommended the use of a performance exhaust system and intake. There are several options available, so to find out which one is right for you, please feel free to call, or click the Live Chat icon at the top of the page to be connected to a 997 specialist right away.
NOTE: Additional software programs require the purchase of GIAC's proprietary Handheld Flashloader. Please be sure to also mark the check box next to "Flashloader" above when selecting additional programs.
