My 98 STi power runs

[Tommy]

Here's a couple of power graphs for my car - a 98 STi version 4 with full decat and a green filter. They were done pre- and post-rebuild of my engine (after oil pump failure pooped the big end bearings). I hadn't owned my car for long when it failed but I could certainly feel the power difference after I got it back.

Pre rebuild. Run on Dastek rollers:
