I thought the extreme kit put out 160kw ATW.Or so it's advertised.
That was done on a hub dyno so you probably want to take around 10% off against a roller dyno.
When my car was tuned on the VAFCii/DC Sports Headers/K&N Typhoon CAI/Custom exhaust, I made 126kws on a DTS Dyno.
Now I've got Toda Headers/Metal Cat/Skunk2 Catback/Stage 2 Cams/Titanium retainers and springs/Custom Intake/RBC Manifold, I was pushing 150Kws @ the wheels with pinging and dropped it to 143kws odd. This represents almost 40% gains from my stock run with NA mods.
