I believe the e85 tune needs different injectors. I wouldn't bother with e85 on a spark though, fuel economy will go down 10% right off the bat. Wouldn't be worth any tiny performance increase.
Vtech says to upgrade the injectorsE85 tune needs nothing other than E85 fuel. But I wouldn't use it. It limits where you can get your fuel from because it doesn't run well on regular fuel. To each his own though.

Yeah I'm sure the duty cycle is very high though. Sure you can get away with it, but not recommended usually ha.There is quite a few on here running stock injectors. They were told upgraded injectors were recommended but not necessary
