I haven't read through this whole thread.. but thought I would add this
Here is my 2010 V6 Camaro. RED = STOCK, BLUE = Bunch of bolt-ons and tune:
Here i my Focus ST 2.0 4 cylinder EcoBoost. The only mods are an axle-back, resonator swap and a tune! BTW, it definitely doesn't need to be "high reving"
Now, if my Focus wasn't WRONG WHEEL DRIVE!
