Only turbo's can be tuned and not the regular V8's

Please clarify guys..
It's always easier to tune a turbo motor (much more bang for the buck) than one that's naturally aspirated. From what I've heard, the N54 is underrated and most are actually around 330 HP with no mods. The 550 has 360 HP, so you're not losing much with the 535 and you're gaining alot in the mileage department. I test drove a 550 and was getting around 15-16 in town driving it nice/normal. As much as I liked the V8 grunt, that sealed the deal with my wife against that car. An +1 with everyone else for going with the '08. L7 is the critical option IMO. I didn't even consider cars without it. You won't be disappointed.
