zzp says "It is only safe to spin an L67/L32 to ~6300 rpm on a stock balancer. Going over that can cause bearing failure, flex plate failure and power loss due to harmonics" is that what people follow or it just a "sale's talk" for people to buy the balancer? my shift points are

1>2 52
2>3 103
3>4 151
2>1 45
3>2 91
4>2 143

1>2 6200
2>3 6400
3>4 6400

fuel cut off
