Stage 1 maps are for cars with stock headers
Stage 2 maps for aftermarket catless headers EL or UEL
E85 maps are all stage 2 maps however shiv advised that stock cars could run the stage 2 EL E85 maps due to E85 being much more knock resistant than petrol you can get away with stock headers
Stage 2 tunes run more timing advance and a bit richer than stage 1 maps as they assume you have catless headers. It ok on stock car on e85 but dont try stage 2 on petrol unless you have aftermarket catless headers.
It does tend to run a bit rich on stock car and you can lean it out a bit on e85 to get a bit better economy and likely a bit more power if your keen they tend to run mid 11 afr up top you could lean it to arround 12.
see my earlier post in this thread with links to shivs posts on this
