flat throughout

[foxy30]

hello again- just put on fmf fatties and powercore 2s on an 02 banshee and it seems much flatter throughout whole rpm range.rejetted main at 290,left pilots stock.

 

 

I am at 0 elavation and 30 -50 degrees, air box is stock, bike is stock

 

 

can anyone help

your jetting sounds right ... but arn't Fatties suppost to "even" out the powerband ? maybe thats why it feels flat (Even) across the powerband.
