The WORX on Subaru WRX STI

These number are compiled by BlueF from Nasioc. (thanks for the hard work)

I spent some time compiling numbers for 08 STI tunes to date.

There may be some errors/omissions… if so, please feel free to shoot me a PM so I can update this list.

As always, numbers without specifics — conditions, data logs, etc — are just numbers and should not be taken as anything but a gross comparison.

As mentioned above, comparing different cars/dynos/mods/tunes/conditions is ONLY A SMALL PART OF THE STORY… fun to look at tho.
