That could work out nicely if they were there for the install, especially if they observe more than help. It would be like usability testing, where they could make note of any confusion/uncertainty you run into during the install and use it to improve their instructions. It would also be nice to have them right there to directly discuss the various concerns that have come up (under-hood heat, hot-side of the turbo so close to plastic parts, etc), and any other questions you come up with during the install and initial test drives.
