i hear what you are saying about how finely tuned they are but the fact remains that the srt6 is much lighter and produces more power but is still slower according to the numbers these 335i owners are touting. i just dont see how.
Newer technology. V6 twin turbo vs a dated supercharged V6. N54 has way more potential when it comes to mods and gaining a ton of power with little mods. Turbo for the win all the time on smaller motors. The N54 could have 306-335hp STOCK 295-330ft lbs stock too. There are so many BMW models and trims it makes my head spin haha.
In at least the US market, the N54 engine has been characterized by a very large number of High Pressure Fuel Pump (HPFP) failures,[26]
On 26 October 2010, following an ABC News story about HPFP failures,[27] BMW announced a recall of vehicles with the pump in question from manufacturing years 2007-2010.[28] A class action suit has been filed against BMW regarding these problems.[29]
Luckily I believe that is an easy fix and I am sure they have fixed the issues with the pumps. Other than that, very stout cars. Direct Injection is pretty scary though when you think about it. so much fuel pressure and a dirty burning engine.

As for launching goes, I have a SRT-6 with the DCAI and that is it. Always leave TCS off when at the track and on the street for best performance?
