The guy referenced is none other than Ethan Bayer, part of the SRT team and also Mopar Stage kit development engineer. Good thing he was there to explain the dyno results by showing them the datalogs. Also there were Dale Seeley of One Lap and Scott from Maxxfab.
Lone, the toys are the option part of Stage 2. Quick and dirty.
1. Racegas switch = + 20 whp to 380 by using 100 octane fuel (or water injection to control detonantion)
2. Dial-A-Boost = four setting switch that allows the on-the fly selection of either of two drag race launch modes (tri-stage boost levels set by gear) or two dropped boost levels (7 and 12) for low traction or training scenarios.
3. Intercooler sprayer = +5whp bump from better control of intake temps. Controlled either by manual selection or by the computer using sophisticated algorithms to head off increased temps by spraying before temps get to high
