Do you have a wideband as well? You'll need to get it on a dyno if you don't. The canned tunes available for download are pretty safe, but it's always best to get your a/f checked. The canned tunes in general aren't horrible but I view them as a starting point more than an end point.
Jotech can do it for sure. They've been tuning MasterVu's car with it for a while. Not sure what they charge.
