I currently have a 97 sti type r Impreza. I'm looking to take more power out of it. It has a full 3.5 hks line from turbo back and a Large hks fmic. Boost is set to 0.8bar on a manual controller. I have changed the gearing to uk ratio for longer gears on the bigger roads. What's my best next step to bring more power out of it?

ESL to start with with those mods then that's only the start of a long road. The list is endless.

No not mapable and about a bar to be safe as you can only get 97 ron. What ecu is in it ?

Standard ecu controlled boost on that model is 1.1bar. I have run mine in near enough standard form at 1.4bar mid trailing to 1.25 at 7k (440cc, vf23, OE TMIC, 99ron).Thats mapped via the esl software/hardware.
