Simple. Every dyno reads differently. ALWAYS at very least convert absolute gains numbers to relative % against baseline of unmodified car power on that dyno, if you want to do any rough comparison between numbers measured on different dynos. What might be 120 hp on one dyno, can be 220 on another. Having at least somewhat known approximate baseline of stock car dynoed on both dynos still is far from reliable means, as numbers may differ due other variables (eg. ambient temperatures/air pressure in different days and such, or cars may have different gearing from different wheels/FD, or dyno operators can also manipulate readings), but may at least approximately land in ballpark.
