How did the tuner know what timing the engine is running?
Did he alter the timing while plotting for max torque through the useable rpm band?
Remove the rotor button and check there is no carbon tracking where it goes on the shaft.

The motor is from a low mileage Explorer from a salvage yard. I bought a new damper and many other components to convert it to a Mustang front dress and carb. The damper was from Ford Racing and had very light indents in the finish that I used to set timing to get it started. They were extremely hard to see so I bought one of those tapes and installed it. Before I put the tape on I wiped the damper with acetone to clean it and what marks that were there disappeared. The tuner adjusted the timing on the dyno and I'm not sure exactly how he did it, but it seemed pretty good for the first 1800 miles. I've had the rotor off already, but will remove it again to look closer. Thanks
