Keep it and run a small nozzle, with the T70 and a PTE you wouldn't need a lot of Meth to keep the temps cool before the E85 hit it.
I'd spray a little on cold days/nights but on those 80 + degree days run the alky knob higher. Since ambient temps change the MAT temp due to inlet and air going through the FMIC you can't just set the alky to one setting.
The amount of alky I'm suggesting isn't a huge kick DC % wise so you might still need 160's if you have a very power GN on E85.
