Read below for some dyno numbers and info:
The IS's 30 WHP advantage and 40 WTQ advantage can be easily bested on a 335i by a simple $850 tune. Read below for that explanation:
The point I am trying to make is, I hope all the people that bought their IS's thought it was sincerely worth it. If you are coming from a Warranty Perspective, then I can completely see it but otherwise, somewhat hard to justify.
Then again that's just my opinion!
Easily bested? The tune puts it on par with the 'is' and I am not sure what Shiv is talking about when he says in statement #2 "the N55 with 7DCT" There is no such animal that I know of. And you also forget to mention the overboost the 'is' has. And you also fail to mention that Shiv also states that you shouldn't look for anymore output due to the single turbo. So I would think that the 'is' with the N54 is a more attractive car if extra HP is your thing!
