Dyno Vs.Drag Strip Testing

I’ll jump in with a little experience I had. On my first stand alone fuel injection set up I had a well known tuner set it up on the dyno. Took two days to get it sorted. That was after I had it on a run stand for a week setting up the base tune. I learned more about the software and how to tune it in those two days than I would have learned in months trying to drive the car around with the laptop. The HP the engine made was not the main focus, the HP came as a result of setting up a safe tune with multiple maps for different boost levels and different fuels. Cost me $700 and in my opinion the best money spent on the engine build.
