2006 RXP - Missing RPMS

[Marc3753]

Recently got my 2006 RXP back has stage 2 set unsure about the prop though. GPS at 71mph at 7700 rpm, and 8.7 lbs of boost. Running stock tune. What could be the reason for my RPM loss?
Last year couldnt get above 7900rpm with
50LB injectors
XXX CHARGER
With the stage 2 set up.
Xxx charger was hitting 12.5lbs boost.
Any insight would be awesome

Pull the pump and see what prop your running.

I'd throw in a new set and see what happens. Also looks like your prop is has to much pitch in it

Should I try a 14/19? I was told it was a 15/20 by the previous owner

I'm running a 14/19 in my 06 rxp bone stock and I'm spinning at 7900 to 8050 rpms with a full tank. Gps speed at 71.4 last week. I'm pretty stoked with this performance

Been using strava for mountain biking and running for years and it works great for the water too
