Isn’t that contradicting? How is it cheaper with countless hours of dyno time? or even less time consuming?
I'll agree that there is a learning curve with using whatever software and understanding all the parameters, but in essence, you are paying yourself for your own time. Yes, you may need some time on the dyno (or at the track) to verify that you have WOT dialed in, but, in the long run I think you definately come out ahead with self tuning.
