Anyone try e85 30% 93?

When I have my BMW 335 five with the in-line six. I found that if I put 30% 85 and the rest was super, I found that it subtracted a 10th of the second from my quarter-mile time. Has anyone tried that with the CX five?

I think that the folks over at Burger Tuning have reported gains with an E85 mix on their most aggressive map, which is designed for pump 91-93. I don't remember the ratio they used though, I want to say 15% E85?

If you head over to their forums and browse the Mazda 2.5 Turbo thread, you might find this info and possibly some dyno charts to go with it.

Up to 30% E85 can be used on map1 or map2 for increased performance vs pump fuel alone.
