With our ZZP LHU Regal PCM Tune setup for this kit, it will allow you to run any mix of e85/premium gasoline and the PCM will adjust the fueling, timing, and boost specifically for it. Each car supports a different ethanol % depending on air temp/density, power level, etc.  Some supporting mods may be require like a larger fuel pump lobe, larger in tank pump, etc. Please consult your tuner regarding what an appropriate amount of ethanol is on your setup.
