If the engine was stumbling around 4000 it would have been as clear as a bell on the chart during the pull and there would be no need to run it through a full pull - or beyond. A skilled tech can listen to the engine, watch the gauges, and keep an eye on the computer screen all at the same time during a session to make sure that he doesn't blow your engine.
A skilled tech would have listened to your initial complaint, done a couple of test pulls (after checking timing and dizzy) to 4000 RPM or so (maybe), and if they looked good - he may have done a full pull. But he should never do a full pull unless the motor was making good numbers.
If your engine had any sign of erratic or otherwise unstable behavior at any time during a pull - he should have immediately stopped. And going beyond your instructions of 6500 RPM limit is simply insane.
