If I put a race gas kit on my 2007 M8 will I have to run 100% Race gas(100 octane) or could I mix 50% 91 octane and be ok up to a certain amount of boost pressure? From what I understand is the Pump gas setups on M8's you can only run around 7lbs because you run out of duty cycle?
Thanks in advance.
