I currently run my car on optimax and octane booster to keep it around 100 ron. I want to fit a full decat system. I do plan on having it mapped, but for now just wondering how it will run? I have an STI panel filter as well. everything else is standard.

Any advice would be great.

Cheers

With a full decat you run the chance of it overboosting slightly especially in the colder weather. With the fuel you are using you shouldnt have to worry about detonation. I ran my 93wrx quite often on supermarket 95 ron unleaded with only the second green light on my knocklink occasionally illuminating

Hopefully it will be mapped in less then 1000 miles anyway.
