    I have a R&D CDI with timing, rpm, powervalves controls- It made a noticeable difference for sure- If the protect controler has similar controls then its probaly a similar unit, so i would pick one up, they also increase spark power. As for the prop you might want to step up to a taller pitch for that HO pump- cause that stinger2 is great for low end and mid power, but will take about 100-200 rpms off top- Most people run a stock stinger with the D-plate and a Jetworks control valve to get the low end punch- then just a good performance prop will do. Also reeds will be another addition- most people run VF3 reeds, adds a solid 100 rpms. ALso 50/1 is rather lean- most people run 40/1 i believe
