I tried to setup a GTech Pro today on my truck, but I can't get it to calibrate the RPM. It attempts to collect this from electrical noise, but evidently the SRT is too "quiet" electrically. I tried it on my 98 2500 rockcrawler Dodge with the 8.0l truck v-10 and it works as advertised. 
Seems like other Viper owners have experienced this as well.

I haven't tried any electrical besides the two 12v outlets in the cab yet.
