You will really notice it on the bottom end. Haven't had enough time to ride it to see what is on the top end and to be honest I don't care about what at the top anyways. Are you running larger tires? If not, it's really going to kick in when the clutch engages.

I ended up with the sport utility (non-EBS). It came with a red primary, purple secondary, billet helix and 47g billet weights. I hated the engagement with the red spring as it was near 2800 RPMS, so I ended up buying a gold and now it's perfect.

Just a thought, you could try just changing out your primary spring to an EPI gold or red. You can usually get them for $25 on amazon. Red will increase your engagement600-800, gold 300-400. Gives you a little extra pop to get the heavier tires spinning.
