This is really a two part question on Perfect Pass. Boat is 2008 220V with PP Digital Pro. It's generally me surfing with my wife driving. As I add more weight to the boat she says the PP is all over the place. I experienced it first hand last weekend when I was finally at the wheel pulling other riders. I know there are some tuning options that should help as the boat gets heavier. Has anybody successfully tuned theirs and have some recommendations on settings?
Second part of the question is will the GPS upgrade remedy all of this and hold a speed even under heavily weighted surfing?
Thanks for the help!
