I just installed a swamp series slip on, K&N air filter and HMF optimizer (Track kit) on my 2009 Grizzly 700. Bottom end is great but around half throttle it falls flat and starts to sputter. Top end seems a little worse than stock. The optimizer settings I started with are 3/3/4. The HMF site gives two different optimizer settings depending on which web page your on. 3/3/4 or 1.5/1.5/2.5 Which one is a better starting point? I've also tried adjusting the optimizer settings up and down with no luck. Would really appreciate any advice, thanks!
