Rekluse experts please

[bones150]

Hello 2012 ec300. installed recluse core and set up as recomended. So far not happy and have race saturday. have a rekluse in a 450 and it works butter smooth pro series. In the gas gas it shakes and growels and is not smooth at all in tight tecnical terrain. Only thing I like is dead engine starts are incredable. in gear hit gas as I kick and gone. holeshot king. I hope someone has a set up solution for me. I loved bike without rekluse but thought it would even be better with. so far not the case.
