Vinson with HMF ECOSYSTEM lost 8 MPH

I installed the eco with the dynojet kit and a K&N filter and lost about 8-9 mph on the top end. does anyone else have the same problem. I even followed HMF's recommended jetting specs. any thoughts???

If there is any bogging or sputtering your jetting might be off. Their recommended jetting isn't always perfect depending where you live.

there is no bog. the motor pulls hard all the way from the bottom but just falls of on top. it goes right to 52 and then stops pulling. I can't imagine one jet size would make a difference.
