Don't get me wrong. Happy to be proven otherwise, but that is a very large gain and I can't believe it unless I see proof.Wow ok... I'll get it uploaded,
That's at the lower end too as I have a sports cat and stock back box.
380/400 isn't uncommon.
If it's true, then amazing, happy days, wish I had that engine.

Then it's downpipes, intakes, intercoolers, turbos, exhausts to get more.
