When you put your External Intercooler in you need to monitor your AFR's, and you will adjust them with your RRFPR, the next would be a flashed ecu and or valve springs to do 8600 rpms or more,

Riva ECU, Valve train update, CMD with auto tune..

Or just drop the running gear into a MSX..

Any way question i have for you was your x charger and 42lb injectors plug and play? Did you have to change anything ECU wise? I was told that the map sensor would auto calibrate for the 42lb injectors and the x charger considering they were oem.

BryanP - Been around Polaris my whole life and even raced for the Polaris team. Darts MSX conversion is fast and reliable and I even won a race or two on it. If it was as easy as plug and play from a RXP to a MSX I would do it.. However its not that easy...

4TECGUY - 42's with X Charger stock ECU no issues and it was a night and days improvement.. Just DOO it..
