From what I have read in the MSD Troubleshooting forum the distributor pickup either works or doesn't. So I do not know if replacement will be the solution. Same goes for the 6AL box according to MSD tech support. Or maybe not.
Something somewhere is wrong.The car basically runs fine except for that continuous hesitation which sound like misses. It gets worse as the engine gets hotter.When fully accelerating there are no such misses to be noticed. Only when driving at a steady speed at around 3000-4000 rpm.
What else is there to check?
Double check the gap... I had this issue a few months ago when I replaced my dead pickup. I couldn't get past 3000 - 3500 and the motor would break up, the tack would go berzerk and the car was bouncing off the MSD rev limiter.

Does your tach jump once it reached 3500 - 4000?

Once I passed the 3000 - 3500 rpm limit the tack started registering numbers beyond my rev limiter (even though the motor was still at 3500 rpm) and I would start missing/breaking up from the cyliner deactivation.

It's hard to measure that gap... I thought mine was OK and I was off .010, double check it.
