Chine walk is just a sign you're running good.
There are some excellent articles on causes and effects. www.kencook.com has a very good one.
Understand the cause, and you'll understand what to do. You have a rotating wheel (prop) spinning clockwise. You have a large object (hull) balancing on a small piece of fiberglass. The prop will always try to torque itself over to the right, the hull *wants* to go straight. Two opposing forces are at work.
First thing to understand, you do NOT drive out of a walk, you drive to prevent it from starting. Driving a high perf boat is a constant left turn, with small right adjustments.
Take your sled out, during the week, with minimal traffic, and with lots of room to manuver, get it up on plane, and as you trim up to speed be in a sweeping left turn. You'll feel the boat get up on it's pad, you'll feel the balance point as you drive against the prop torque. Small adjustments, think of riding a skateboard in a 40 mph cross wind.
If it starts to wobble, trim down and start over, don't try to fight it, you're too late. If you attempt to react to the boat, you're too late, you must make it react to your driving.
Best advice, find someone on the clue bus to spend a half hour on the water with you, it's easy to teach, difficult to describe.
