no surprise here,
even my ex stock M6 F13 Competition was as fast as 458 italia (regular)
(after piggy back tune it was just insane fast: 6.0s 100-200 and 5.3s 200-250)
Ferrari has a problem that every car may have differet power.
You can check GT Board Videos, some 458's are as fast as 997 Turbo PDK, some regular 458 are faster then speciale's, some are just a little bit slower than aventador...
It all depends about specific car...
my 458 is pretty fast for stock:
100-200: 6.7s on regular conditions, 6.1s best winter time
hopefully one day i'll find someone with new M5 and record a roll race;p
