The operator will have the graphs on file.Ask him to send a copy. Include all pages,sfc and a/f, temps,cfm flow if any of these things were recorded? Dyno Jet by itself does not record anything other than hp/tq. Hope he had support equipment when tested

You can make a piston stop tool easy. Buy a spark plug non fouler from a parts store. Drill and tap the center for 3/8-16 threads. Find a bolt that's threaded 2-3" and thread it through with a jam nut. You can adjust the bolt depth as needed based on the plug angle or chamber shape. I did this to find tdc on my 390 since nobody locally had a piston stop tool in stock.

It was done in my class. Me and my friend put it on the dyno. They erase the computer every session (6weeks) because they have lots of kids dyno tuneing cars. When we did mine the a/f sensor didn't work. I can post them when I go home next week.

thats fine. A dyno tune is what you want. You just got test results,nothing else.Tuning on dyno usually net 5% or more increase depending how well you tuned the car before testing. Fuel curve is very important. different fuel curves for different drivers,,,
