Okay.
You’re wrong.
Simply put, a poorly functioning converter will make both the ET and speed numbers look bad.
Period.
I’ve seen that scenario play out countless times in the last 40 years.
Unfortunately........ the best way to see how bad a converter really is...... is to replace it with a good one.
IMO, the converter you have is a poor match for the motor combo....... but it’s not cheap or particularly fun to find out if I’m right or not.
I’m not implying it’s the sole item responsible for the poor performance though.
When I learned all this stuff, there was no internet, and not a lot of people to ask for advice........ so you tried things and just figured it out.
Or you didn’t.
Sounds like you have a plan....... so just work your way through your checklist and see how it goes.
One last thought......... which do you feel is the more likely scenario.......
A-the motor is down 100hp, or
B-the converter is a problem
I’m going with..... C-it’s some of both
