Agreed with Art...drop down the pitch of the prop if its a 21 to a 19 and you will get better control...Im currently running a 21 but am changing to a 19...If you could switch to a 4/5 blade prop go for it, but just remember your top end is affected. I have a 2008 Tahoe Q6 and its carbed and I just got perfect pass put on and it is night and day difference. I would never trade it for anything. A good driver will be able to get good control of the throttle but when we tested the drivers good timing to a gps handheld unit, it actually varied within 2 mph while the RPM didn't show different....We got perfect pass stargazer and it literally keeps it within +-.20 of a mile. I board at about 23.7 and it will stay between 23.5 and 23.9. In butter it will stay at 23.7 and its all GPS based. We trim to 1/2 up and it does great. Perfect pass mentioned integrating a trim function that adjusts that as well per rider.
