Can I get some help understaning what my converter slip number is telling me?

3350lbs, c4 tranny @1:1, 3.73 gear, 28.0" tire, 7000 trap rpm, 9.73/140 mph, 9" converter stalled at 4400.

Looks to me like about 11.7% Is that correct? What is that saying? Good? Bad? Need to change something? Seems to be running good but the slip number seems higher than what I've seen discussed.

I understand my c4 is non-locking. Is that the difference?

I got 12.967 in the 1/4 and IMO is too much. It needs to hang onto the motor better. Not necessarily too loose at the bottom, but at the top it is.

Forgot to say I'm using a 100 shot (dynoed as 157 to the wheel).

What's a solution to that?

It needs to go back to the builder and adjusted. Does it 60' good or are you on the edge of spinning the tire?

60's high 1.3's, chirps a 10.5 slick and sticks. Pulls front wheels about 6" for about 10 feet. Feels good. No complaints. Just wondering about the number.
