Also, dont ask for printouts or snapshots in jpg, go ask the dyno shop for the "RunFile_010.drf" and "RunFile_033.drf" files (and all other files for each pass you made) and download the Dynojet program so you can see all in your own PC and make informed conclusions about your runs.
When I go to the dyno I always stick my USB drive in their PC and download all my runs for later viewing at my PC. Dynojet has a website with a copy of the program to view these files, excellently useful.
Don't let them tell you how you cannot do that, because you paid for those runs. If you didn't, then they are your friends and shouldn't have a problem with you doing this.
