Just curious if you needed to a 4-6% more fuel as VP recomends. I will be going from a tune on 110 to this Q16 (116) and wondering if it is going to lean it a bit will the extra octane be enough to be some what safe or should i add 5% to fuel map to start with?

 

guess I should have searched it first..
