BigDog05, You want ot get your sled running clean on the botom end adjust needles for a crisp trotle response. Once you ave te botom running good you can adjust the top end with your pitot tube jet. The bigger the jet the leaner you will run on op end. Watch your EGT's and this will be your guide for proper jeting. I've found that on differnet days and (temp., altitude) I will fine tune performance with the pitot tube jets. That's the beauty of the Bender system it is quick and easy to change the pitot tube jet.
