here is GIAC new
New GIAC Version 2 software release for the 997TT...
Date: 10/3/2008
GIAC is proud to announce a new software version release for 997 Turbo applications. This new Version 2 software calibration updates and enhances the very popular GIAC 997TT program released in December of 2006. With 8 - 12 peak wheel torque, 5 - 15 wheel horsepower (temperature/ octane dependant) gain and more area under the curve over the previous version, existing customers will feel a significant difference and new customers will be elated. The peak boost level hits 1.4 bar with 1.2 bar of pressure throughout the upper RPM range. With the right combination of intake and exhaust, this program can yield gains on pump gas of up to 88 horsepower and 78 foot-lbs of torque over the stock program. When coupled with an exhaust upgrade the new programs maintain exhaust gas temperatures and knock correction that is very close to that of a completely stock 997Turbo.
The attachment plots three dyno runs:

seriously folks, I go through this with my own personal business... which isn't related to HP tuning but the same question... what is the best
First take into consideration a few things... and I am going to state the obvious, buying an exhaust for sound is the most retarded thing I heard this week... sure you want great sound, but let's be clear... without sacrificing drivability, vehicle warranty, HP, torque, quality...etc
As for the best I came with this formula...
-First the manufacturer, reputation, there for your questions, warranty to match the vehicles
-Manufacturer going to be there in the future? how long in business, engineers background, testing, etc
-Porsche? are they going to give you a hard time?
-there is more but these are the major ones... just tired (1:39AM)
Jim
-quality of the material?
-affordability

FYI, Akrapovic is the supplier for the OEM 997GT2 Ti exhaust, I think their stuff is probably pretty good.
