I dont think you should.
I think the car should be tuned properly on e80 or e85 before you track the car.

I wouldn't. The whole reason you went E85 was so you would not have to spray meth. It sounds like you have enough injector and pump to keep it safe.
I have a similar setup and have been good with the E85 all the way down to E60.
Turn your boost down and log your runs. Based on data, creep up onto higher boost.

45-50lbd base seems to be the range. I run about 48ish. But depend on your set up too.

I would keep the Meth in case you run out of injector. I would tune it first 100% E85, then if needed in the future for injector headroom I'd tune the Meth in to stay away from 90%+ IDC pulls around your desired AF/R.
