Why not install it yourself? It is a pretty easy job for a DIYer. However, if you do have someone install it they shouldn't charge you more than an hour's labor. If they're good they can do it in @ 30 minutes, including removing the glovebox. How much should I pay for an install of this chip approximately. I have the price on the chip from Dinan. Also there seems to be a clicking noise in the rear driver side area - any clues?
