I don't really agree with the x-car + tune is better than y-car argument.. If that's the case then M3 = ESS SC is better than an S4 (or most everything else) with a tune.. Apples to apples comparison the M3 and the 335i stock is better than the RS4 or S4...
My only point is that comparing the M3 with the S4 is a ludicrous comparison. Audi makes a car that's in the same class, the RS5 and you wouldn't do a RS5 vs. S4/S5 comparison...
