You love to do things the hard way. Costs money to go fast, as you know. What we are saying is that do it right and it will be consistent.

Think about it - you had that converter with the old combo, AFAIK. Now the combo is totally different, do you expect the converter to behave the same? Converter should always match the combo. It's gotta be an uphill battle trying to tune a motor that is fighting itself. I'll bet your data curves will look completely different with the right converter.

Look at the pics you posted in your other thread - top left, the first two data inputs - engine speed vs. driveshaft speed, maybe kinda important ones? The first pic on the 9.79 pass shows a ratio of .52%!! According to your readout there, the DS was spinning at over 13K RPM. Thank Marty for doing a good job balancing that thing.



Now look at the 2nd pic, the ratio is more than 20% higher and see how much it picked up. Imagine if it was up in the 90% range...might not be possible to get it working that efficiently but you get the idea.



Don't mean to talk out of school here, just trying to point out that the blower does not overcome all maladies.
