We took a 2003 996TT with a few mods over to the dyno to get a base line and then install a IPD 75mm plenum and t-body. Here are the results.
The car was never taken off the dyno. The stock plenum was replaced with the IPD unit with in 2.5 hour from the initial base lines.

The cars mods as listed:

X50 K24 turbos
Fabspeed exhaust
Fabspeed Headers
GIAC ECU Tune (race)
Diverter valves
EVOMS Airbox
Hitachi MAF
BBI Coil Packs
100 octane fuel

Here are the dyno results.

Here are all the runs on one sheet.

The Numbers below are sampled at every 100 RPM. Makes it a bit easier to see the per RPM differences.
