I just got my 08 700xx and ordered a full HMF sport series exhaust, Pro flow K&N, and the HMF optimizer. I just wanted to know what you guys have your optimizer set at? On HMF website they say 1.5/3.5/3.5 will that be the best for what I have? With the Pro Flow K&N kit should I run that with the air box lid off? Thanks for any help.
