EDITED to make Modertaor Andy W. happy:
Dan,
I spoke to JJ (Lightning guy) a couple weeks back and he said he hasn't installed the Apexi on a Contour, but said it should be straightforward and would offer a small discount on installation for the first couple Contour installs.
He said he has access to a dyno ($150/hr) and can tune it for you, too.
Try giving JJ a call at 410.259.8737, and tell him "Pete from CEG, who called you a couple weeks back" told you to give him a call.
Good luck!
~Pete
