Pretty straight forward here whenever you approach tuning any other kind of fuel other than your usuall pump gas whether it's c16 ,q16,e85,or even meth/water inj at the time of actual tuning is there any specific amount that you can't exeed ?
For example if I want to add c16 to whatever platform I am runing on pump gas can I just put a full tank of c16 and start tuning ? Or do I need mixture of pump gas and c16 to start with and then gradually have a full tank for the tuning session? and can this differ from a fuel to another?
