Or they have no knowledge of carb tuning and expect the Dyno people to give them the answers to why the engine is running poorly and hope it will run better afterward.
And the GOOD dyno operators have the ability to get the air/fuel ratio in the ballpark in a few pulls. Timing is different question.
I have seen a bunch of Pontiac engines hurt by shops because they said he could get them another 15 "Bragging" hp by throwing 3 more degrees of timing at the engine. 99% of the people do NOT need optimal timing for their engine and Optimal Timing is not a curve but is a GRID of different timing points based on engine rpm and load across the whole grid.
Optimal Timing takes less work on a drag race engine running on the dyno as it is one set of load points.
This is the street section and you can have a nice running street engine but it will not have optimal timing,
PERIOD, as true street engines have lots of engine load points based on location, rpm, load, etc.
