Best tune/mods to get 100 HP gain?
I got my F85 X5m with 12K km on it a few years ago. brand new basically, but now I was wanting to get as much power out of it as possible. it's got about 35K km on it now. but, I think the velos tune was $1700 just for the handheld. seems excessive. What have u guys used that got the best results recently?
Thanks.
