Okay, I finally got mine dynoed. While not in the same league as Knotched and Foozrcool, I was pleased to see mine's made the same power as Knotched's first dyno run, despite having different mods.
What I have here is: Berklee straight thru rear muffler, US Galant 90mm intake, K&N filter, removed under-bonnet front rubber strip, removed plastic engine cover, and running 98 octane fuel.
So for people running these simple & affordable mods, this is roughly what you will recieve.



The video has been posted on YouTube also, and shows 139kW and 200+km/h. It is the ONLY video of a 380 having dyno power run.
