surpip06, there is a lot of derogatory information about ARAO on the web. Do a search for ARAO engineering on www.speedtalk.com
, and do a search for "ARAO customers" on the internet. Read this thread from Corvette Forum
. I can't say any of this is true 'cause I have no experience with them, but I would be VERY careful and wary before you turn over that many $$$$.
