I called some gas stations and their fuel here is best b/w 51 and 55% ethanol.
Want to know if something is wrong with my car, maybe not holding boost high enough maybe there is a leak, maybe ask bmw why car is slow.
I just can't get 1/4 mile better than 11.4 stock with perfect launch.
Tuned cant better than 11.1
