What gear did you run it in?

How about the torque, any increase? That's what you "feel" when accelerating out of low revs.

Yes, I noticed it too..., the best is to do your dyno run on 5th gear because 1:1 ratio. I dont know why the shop decided to do it in 4th gear!?!? Probably for safety reason??? hmm

But I dont really care how much power my car make.... 100kW or 400kW, I only interested how much gain my car made stock vs. with mods...., I think it gained around 16% power increase... not too shabby for NA engine.... actually it's very impressive gain.

400kw would be nice.

Great work on the mods, really good gains. I am keen to check it out and start a shopping list myself.
