Fuel Line Extension / Stumble Fix Mod for GR STI's
Has anyone done this mod yet? Was browsing around IWSTI and found this:
Fuel Line Extension / Stumble Fix Mod - Subaru Impreza WRX STI Forums: IWSTI.com
Apparently it fixes the stumble found in the GR STI's at 2500k-3200k rpm from inadequate fuel delivery due to the length of the fuel line. And it also helps with general cruising driveability. The thread explains some minor tunning is required. (anyone with an AP and access tuner race or open source tuners would have to adjust Engine Load Compensation Cruise (MP) and Non-Cruise (MP) tables).

The thread says you can, you just need to reset your ECU and you'll run a little rich where the tune in the tables would be. I'm gonna do it but i'm gonna read into changing the tables in access tuner race before i do.

I used this. Little expensive but its plug and play. Feel free to call Stephen at IAP if you have questions.
