    RIVA STAGE 2 TUNE AND SOLAS SXX 13/18 is perfect for your setup. You should see about 8300 RPM and about 80MPH. I have been using this tune on my 2016 PX and TX 300, my 18 TX 300 and my 19 TX 300. Idles perfect and runs great. You can flash it yourself with a Maptuner and tuning license

    Or you can mail in your ECU for reflash

    13/18 is a great prop...until you shear a blade off. They are just to thin. I ran one for about 30hrs on my 18tx on a stage 1 tune, and one day one of the blades just sheared off and got stuck in the housing. The ski rarely saw more than 8200ish rpm. I was lucky it only cost me a wear ring and was close to my house so I could just tow it back to my dock.

    I'd do the riva racing intake and riva flash, catch can and leave it. You could have your stock prop depitched to get your RPM up. That's about as good as it gets for an rxp unless you want to go to a cam and charger, injectors etc.

    You can get all that stuff on the forum store and Jerry can ship it to you anywhere. coupon code is greenhulk

    Just make a custom intake like the one jp sells. Itís not hard. You need the 4 inch filter thatís sold here on greenhulk and riva Racing, a 3 inch to 4 90* silicon hose which you order on amazon for less than $20, and a 4 inch diameter aluminum pipe (also on amazon) so you can connect the filter to the silicon elbow. Obviously you may need to cut the pipe to size if you get a longer one like I did. Pair this intake to a riva stage 2 flash and your right there at 80 mph. When I did everything I did the intake last and the intake alone gave me over 200 rpms. Mods are in my sig.
