race gas question

So i "think" you need a tune, but how would dumping a few gallons of 110 or c16 into my vf39 2.0 at the track affect it? Do you have to be tuned for it? Will it be ok, just not as significant of a difference if it was tuned for it? Or is it a bad idea all together?

Thanks in Advance

Running just a little to bring the octane up a point or two would help but running straight 110 or c16 without a tune would not help and may actually hurt perfomance sightly.

 

if you mix it a bit it smells great too!!!!

 

not good, I snuk in a few gal's of 100 octane before a dyno day years ago and put down 10 less hp.

 

yeah, i was gonna split 5 gallons with a friend and mix it in...so its kinda EH i suppose.

 

race gas = puppies die lol
