2 ZFG Customer Running Very Fast... Under E40 Tune....
Many people call it an E50 tune, but that doesn’t mean they are actually running full E50. There are many factors at play. Personally, when I tested E40, the injectors were already at their limit. This happens to a lot of people. Some can read their ethanol content, but many don’t even have a sensor to measure the blend and do it by eye, so they don’t really know what ethanol percentage they are actually running.
If a Unbroker claims that their E50 tune is faster than Peter’s, then they should show their Dragy data or a track time.
