Nice pick up Ive got a BF F6 as well and their great cars, I've been doing to Dynomite and just got my E85 tune last week and Dion got some great numbers out of a simple set up.
Not happy about 100 octane being phased out. I actually made a special brew last week at the pumps and it seemed to do the trick. You need about 20% of E85 to bring it back upto 100, so far its working for me
