I want switch to e85, smart people click please

It would be 30% more of what you were using, not 30% more duty cycle. So add 30% more of 53%.

Around 68-69%

Do you have a wideband? You should get one, great investment

If I go to a gas station, fill it up with e85 and do that, will it run well enough to drive around for a bit till I get enough gumption (monies) to get it re tuned? My injectors were at 53% duty cycle, last time I checked, so they should be fine with 30-31% more DC.

Or are there any tricks to switching that I should know? Should I turn off O2 feedback at first, or leave it on, and I've heard 30 percent more and 31% more fuel, I know it's close, but I have the option to do either one, so which is better?
