The shop that works on my car and rebuilt my engine and they work with Softronic a lot. Softronic provided a custom tune for my 3.2 bored out to 3.6. After the engine was broken in, it went on the shop's Dynapack dyno, they sent results to Softronic and Softronic sent them back an updated tune the same day. I think they send the air fuel ratio results chart from the dyno runs to Softronic and then Softronic makes adjustments. If a chassis dynomometer isn't used, the engine would have to be out of the car and installed on an engine stand dynomometer.
