Funny Car Launch RPM?

Sounds like the motor is down on power. To leave at 6900 with 3 turns and 30 grams with 1.64 and I am asuming not a national event prepped track for it to not want to strike the tires sounds like it is way rich and the shake he is having at the gear change is a down on power shake. But with out seeing any of the data we are all just throwing darts blindfolded. But is it way rich because of the tune up or because at 7000 it is of off staging pop its.

 

looking at the graph now

60' were between 1.01-1.03 all weekend
330' between 2.67-2.74

this run:
Launch rpm: 6950
clutch: 35.4 gr total
480 base, 3turns
.062 pack
motor is not lean. not overly safe, but still a touch on the rich side.

clutch slips for 1.2 seconds, then starts to grab at 7500 rpm,

locks up at about 8000 in low, 1.8 seconds out, and appears to start shaking at about the same point, maybe a fraction later.

shift at 9200, 2.2 seconds out, still shaking, lifts, hits high, gets back in it, and the car pulls very good through high, no slippage then.
