Fueltown is still out according to my mate, he cant tune his old xr6 flash box anymore so is back on 98 until fueltown have stock of e85. He was running Caltex for a few weeks but it just ran too rich.
You would barely notice the difference between e65 and e70 on the wideband, I just assumed they mixed it on site as the tank was filled hence the inaccuracy's.
