Sorry, but I'm not sure we'll learn very much from your dyno test. If your car blows up we'll learn a lot, however, so certainly thanks for being a guinea pig...

Everyone knows how to make more power from tuning- that's no secret. Unfortunately making more power reliably is very difficult, and it's not like one tuner has the "secret sauce" that lets them be much better than another. If Evolve is making more top end power they are making more heat and pressure and pushing the turbos further off map; they will fail sooner. Unfortunately until they fail we don't know if that's going the be soon enough to be concerned about.

Making power is easy as you've seen now that you're ~30% above stock. Making power reliably is really hard- I like how the Viper team explains what they did for the viper to allow them to do a more aggressive re-map on the 2013 Viper:

"We went to a sodium filled exhaust valve, that allowed us to be more aggressive in our calibration with spark and fuel. We went to a forged piston, same reason, it was able to withstand higher temperatures and pressures so we could again lean out the mixture, be a little more aggressive with the spark and not compromise durability..."

So they changed valve materials and pistons to get ~3% more power through engine re-mapping, while you've changed nothing internal to get 30%. Something to consider... If you want to chase top end power numbers you should really get bigger turbos- running those parts so far out of their designed range is not going to do wonders for your car's long term health. JMHO...

The description of the engine mods to the Viper are here, interesting stuff:
