I finally installed the Evolve tune file, it's awesome!
I immediately noticed the different exhaust tone. There's a new layer of high frequency metallic sound that wasn't there before. It comes when I WOT above 3500rpm and it sound so aggressive. I don't understand how a tune can change the tone of the exhaust so much.
