And the majority of our gains with our 997.1 system are by use of much higher flowing cats, given that we don't have to hit the same emissions targets as the OEM's. We have the same opportunity on the 997.2 once the software obstacle is removed. Comparing cat gains to midmuffler replacement gains or any hardware-only massive gains on the 997.2 is what is controversial.

I will be at a few track events and I did something like this with another 2009 at Sebring. I will be at Daytona this comming weekend and Sebring for the PCS Suncoast event.

But this is GIAC's thread so I'll step out. I was just saying that we didn't see "massive" gains from our stand point (unless you call 8hp massive).

GIAC performance software is now available for Porsche 997.2 applications. This programming offers significant improvements over the standard factory programming:

* Improved crank horsepower and torque gains of 11-14 hp/13-15 ft lbs of torque.

* Improved drivability, with power and torque gains across the entire rev range.

* Improved throttle response for a drive-by-cable system feel.

* Increased torque limits to accommodate additional hardware modifications.

* Stock mode and a handheld switcher are included with purchase. Additional switching modes (Anti-theft, Valet) may be available for purchase in the coming months.

Dynamometer test results measured at the wheels are included here. The graph plots three runs for a 2010 Porsche 997.2 PDK with a pre-installed X-pipe on 91-octane fuel. The first and second runs are performance runs with GIAC programming included to demonstrate the consistency of the software power curve. The third run is the baseline run with stock ECU programming.
