If you use a wet system, the viper is no different than any other car. Install a wide band and start rich till you hit approximately 11.0 to 11.5 between 4000 and 5500. Without any means to retard the timing, the 11.X will retard the ignition cycle enough. That is not the perfect world, but, it gets you there.

What code are you throwing? As was stated, a relearn may solve the issue.

Maybe I need a throttle relearn as we've checked for vacuum leaks and can't find anything. My belt just began squealing a few days ago. It's a slight issue where the rpm stumbles 50-100rpm and will throw a code due to it.

I'd love to stay arrow, but with my hellcat I can drive out another 150rwhp for around 2-3k. Any engine power adders for the Gen V after bolt ons are 20k+, so to be able to squeeze another 100-150rwhp out of the viper I'd be happy. Unfortunately not much documentation of nitrous shots around here for Gen V's and the arrow controller included. Could always go 50-100-150 and watch AFR's on the testing and dyno.
