Sometimes the chine walk comes from sloppy steering. Make sure ALL the slack is out of the steering cables. Also if you're not jacked high enough, the gear case creates lift and will make it chine walk. Alot of people jack till water pressure starts to drop. My Viking liked 1/2" above the pad with the center of the prop shaft. I had 5" setback.
One way to determine if you have the right setback is to run at speed trimmed to your desired angle (hull angle) and get a side view picture. Look at the motor. If it has positive trim (usually a 50' high roostertail is evidant) you need more setback. Trimmed under/ less setback. You want the gear case to run as close to parallel to the surface as possible.
If you watch video's of the v-bottom streams, you will see the driver constantly working the steering wheel slightly.
My little Viper has to be constantly "Snapped into submission" Over 75 mph, you notice the bow starting to slightly rock side to side. As soon as this happens, a slight quick jerk opposite of the roll will straighten it out for 10- 15 seconds then repeat. After a few outings, it just becomes natural.
The EFI motors (not the racing versions) have a slosh tank on the left side that has your high press pump. The pulse pump mounted to the block fills the slosh tank so no other pump is needed.
Did you add fiber reeds? Cheap insurance. A broken metal reed will ruin the motor. Plastic/ fiber reeds rarely break and will not hurt the motor.
Other than that, seat time will train you. Good luck and have fun!!!!
