These tunes are not a good option for increasing power output. Please remember what a "tune" is and how an internal combustion engine works. About all you can do to squeeze out more power on a NA engine from a tune standpoint is to modify spark timing. Our stock tune is already plenty aggressive here, and pushing timing forward further will only result in detonation. This in turn will either cause the ecu to pull timing once the knock sensors pick it up, or you'll do some serious damage to your internals.

The main power output difference between the 3.2 and 3.4 is the INTAKE, not the tune. The 996 intake uses an 82mm TB, the 3.2 uses the same 68mm TB that the 2.7 uses.

My base 2.7 now has an 82mm TB and 3.5" short ram intake with catless headers and a 2.5" exhaust with 100cel cats. Combined with a 996 tune and UDP, my LTFT data suggest my power output is somewhere around 245 hp. Pull the clutch sensor so you stop having timing cut back during shifts, and you now have a formidable setup.
