The 335i is likely a manual as the automatic single turbo cars still do not seem to be making the same power as the manual vehicles. So, at this point, it will really take a manual 335i with meth on race gas with the ST kit to keep pace with a mild supercharged DCT M3 on 91 pump as seen in the vid. The M3 pulls, but the 335i does a nice job considering the M3 seems to get a jump on it and has the disadvantage seen during shifts due to the dual clutch M3 transmission.
The main thing this video shows is Shiv@Vishnu needs to beat stock internal M3's before running his mouth about what this turbo kit can do against more stout BMW's including more powerful M3's. Which right now, as the video shows, is not much of anything.
