shouldnt be hard at all. being mechanically/electrically inclined helps.
dont know if your located in Socal (SD area) but...
i met a guy who just started a shop and will install them for $75 w/mapping.
thats what he told me and wes600rr. i have yet to investigate this persons
knowledge, shop, pricing and touch base with this guy.
From the write up on this site it looks like alot longer than 10 minutes. My dealer did the install free with the purchase, though. And the custom mapping cost 250. My brother-in-law says his local shops in Oceanside, CA don't do installs. Maybe smog rules?
