Smile car vibrates after putting e85 in

I have an 07 335i that is tuned. I just switched the map to e85 from 91 octane. Car is handling it fine until I slam the pedal to the floor. There is no lag, no weird noises or anything until I let off the gas. Car is fine coasting but then when I accelerate the car vibrates/shakes horribly. The car will vibrate after I come to a stop while it's idling. Turning the car off and back on cures the problem completely..until I floor it again. I have let it idle after accelerating hard. I have also revved in neutral. The only thing that cures the problem is turning the car off and back on. I'm thinking this is a computer issue? I just filled up with my second tank of e85 since changing the map. This did not happen before when I switched to 91 octane from e85.
