On earlier models, the mechanical advance can stick. I'm not sure which Bosch distributor you have, but you may be experiencing the same problem, especially if it only happens at high speed. At the 1500 rpm checking speed, it's conceivable your timing could be within spec.
While you have the timing light out, disconnect and plug the distributor vacuum hose, then have an assistant hold the throttle at 3000-3500 rpm. Watch the timing advance on the flywheel scale. It should go all the way out to at least 36 or 40 degrees at 3000-3500 rpms. If it's stuck at 15 or 20 degrees, the mechanical advance is stuck. If you're lucky, disassembling the distributor, cleaning, and spraying the advance weights etc. with WD-40 will do the trick.
I've seen this problem affect many models of Bosch distributors on many different cars.
Good luck.
JD
