I found a RPM activated switch. It will turn on your nitrous system at a preset RPM and turn it off at another preset RPM. You can set it to turn on at 4,000 RPM and turn off at 6,000. That would let you get off the line before the nitrous comes on then it would turn it off just before the shift. With the drop in RPM after the shift the nitrous would be turned back on until 6,000 again. It should allow you to tune the system for max performance and let you concentrate on other things during the run.
