Unfortunately, I do not see much room for improvement on most logs I see from my Flash Tunes. I typically like to keep boost and timing levels safe, unless verifying power gains on a chassis dyno. With that being said, my Flash Tune already pushes the 1.6L Ecoboost pretty close to it's mechanical limits. My custom tune option is really more desisgned for vehicles that DO NOT respond well to the Flash Tune, and need further refining (ie. 91 octane Cali or Canada fuel is usually very poor).
However! I have a new Flash Tune dropping for you guys very soon, that I think you will really like!
Something no one has ever released before for our platform!
