RXP-X impeller stock pitch
I'm looking for the stock pitch for the 2008 RXP-X impeller. Or is there a better pitch that will allow me to gain top speed without losing any acceleration? I love the way it performs completely stock but would love to see more on top end.

No chance to have both acceleration and speed without changing of fuel map in ECU. First reflash your ECU to 8400-8500rpm and after start to pitching stock impeller up for app 2-3mm for the first 60 mm of impeller screw. It cut app 200-250 rpm but gives you add speed and acceleration. Don't forget about changing retainers.

A 15/22 is one of the most overrated props for stockish setups.
