i have a blown 19 foot daytona with a semi-V. if i trim the place diverter up to shoot a rooster, it porpoises violently. it has a droop snoot on a dominator pump. it also porpoised before the droop snoot. i tried a ride plate on it, but it did not make a difference. with the place diverter trimmed down, it is stable as it can be, but trimmed up you cant stay in the throttle. any ideas would help.
