You non supercharged people will not be jelous if you get a new m3 and see the total dominance. Something about aftermarket, no matter what you throw on there, just rarely can match the new oem stuff. IE the new M5. You can drive a blown m3 all day long but get a new m5 stock, let a lone a tune and it blows the doors off.
New m3 will be faster and better than charged with a simple tune and the thrust will be even greater.
