careful there ... if at any time the stability management program modulates throttle (traction control being off ... which it never really is in this car due the stability management) while you are spraying, you may make some windows into your combustion chamber ...

i would look into a window switch for sure to make sure the system is only capable of spraying between 3k - 6k.

also if you can find a way to have the kit monitor the ASM to shut it down when it is going off or monitor the absolute throttle position to make sure it is at wide open throttle... should be easy just time consuming.

PS ... i think its great you are running the crossfire ... both thumbs up on having the ***** to go with the nitrous setup with as few people as we have that have done it.
