Anyone have any info on running e85 on the s63tu motor?
Both on a jb4 setup and with a flash ECU tune..
I had heard before you couldn't use it on these but Joe I am seeing some guys using it and would like to know more.
Thanks all!
Also want to throw out a huge thank you to Terry at BMS for helping me with my X5M. His customer service is above and beyond in everyway. It's so rare to meet business owners like this at all anymore.
