O/P great video, but why only run E25 with the JB4?
The PTF on the COBB car is definitely working as advertised
because i had filled up with 93 2 days prior lol. i tried to run it down as much as i could so i would have some room for e85 in the tank, but was only able to run down about quarter of a tank. I showed laid black 335i my receipt for 4.1 gallons of e85 that i had purchased just prior to meeting up with him in africa lol. 335i tank is 16 gallons, so 4 gallons is 25%.
