No turbo lag. Just 370ft/lb of torque ready to blow in your face at the push of the pedal. Didn't need to floor it, just put it in sport 2nd gear at 30mph, 40% paddle depressed and damn.

Which year 335i are you comparing to? The 335iS has the same engine as the 07-10 335i (parallel twin turbo setup (n54) engine). It wasn't until 2011+ that BMW started using the n55 (single twin scroll turbo setup) for the 335i. Although both the n54 & n55 have about the same small amount of 'turbo lag' the n54 335iS has an additional radiator and beefier engine mounts. The n55 may actually have just slightly a bit more lag but nothing a human could probably notice. So, in terms of 'turbo lag' there's no difference between the 07-10 335i and the 11+ 335iS because they run the same turbo setup. If your 335i is an n55 then it's probably the difference in WHP because on average the 11+ 335i n55 produces at peak dyno 266hp and 302 ftlb trq while the 11+ 335iS produces at peak dyno 293hp and 343 ftlb trq.. If your 335i is an n54 it at stock produces anywhere from 276-287hp and anywhere from 287-296 ftlb trq so not much difference to feel.. I'm assuming your 335i is an n55.. And where are you getting that the 335iS has 370 ftlb trq??
Edit:
Also suspension is the SAME..
