The humps I was originally getting were to 6100/6150, then pulled down to 5800. If it spun the tires then the humps would be to 6300 or so, then pull down to about 5800.
After fixing the air/fuel there normal dead hooks go to 6100/6150 and stay there a few frames then go up. Now if it spins the hump will still be 6300 or so, then to 6150 or so. Doesn't pull down to 5800 any longer. Shows in my 60's & ETs too. I at first thought I had a 5800 RPM converter. A few passes at a track rental fixed it.
