thanks for your opinions!
N/A engines seem to be a lot more aggressive in their OEM KFZW to gain some HP.
It's obviously a matter of dyno effort to get some handful HP, may be together with a good exhaust and fuel.
a lot more aggressive or a lot more passive? lol.
In the USA i have not seen what i would call even remotely aggressive KFZW. You can add a lot of timing on these US spec cars.
N/A cars benefit from driveability and more response with tunes, i would say for performance, but rather a sportier refinement.
Like said HP gains are minimal ~20hp give or take a little on 24v vr6 and 4.2 v8
