Well after trying unsuccessfully for 30 minutes to figure out what was wrong with my TPS Activation Switch for my nitrous setup, I ripped the thing out and went old school. Can't beat the NOS Micro Switch for reliability and it works rather well on my adjustable pedals. The falling TPS voltage of the 6.0's combined with the voltage fluctuation I was seeing on my test meter today tells me I would have been fighting an activation problem forever. Not anymore . . .
