Mine made 270hp at stage 2 on moderate Revo settings with just an intake and a Turbo back de-cat exhaust system.
Added a lot more since then - Intercooler, much better intake, LOBA HPFP and a Devils Own WMI kit, along with a Revo 2+ map and very aggressive settings.
Needs to go back on the Dyno. Peak powers won't be much better as limited for top-end airflow with the K03 and standard actuator pre-load, but the midrange is awesome
