How you got your setting on the W/M controller?

Sounds like you have the boost setting too low on the controller (injection too early). Raise the level to start at a higher boost level or swap nozzle for a smaller diameter if you cant get it to stop. You probably aren't making enough boost at lower rpm's on stock setting to allow it to start early enough. Once it starts building boost, your RPM's are higher so it can evaporate/burn more water faster.

Moved to Propane, Nitrous, & Water Meth.

settings are 8psi mpg start and 20psi 100% only rattles when dsp5 not on stock
What is your max attainable boost level when using the tunes? Have you tried to set the start @ ~12psi and raise the max setting closer to your max boost level?
