OP - a standard 335i is meant to be fairly subtle in its nature, no lag, very smooth linear delivery, its meant to feel like a NA motor, that's the whole point of the standard N54. A 335i is pretty heavy too.

Even tuned its still very linear and can be driven round very steadily (my missus hasn't noticed any difference from standard)

...But JB4 FTW!

Dynos shown for older JB3, but similar results to JB4 flat out. I queried the figures as they seemed very high, but it was a freezing morning and the dyno operator was using a 18% transmission loss dyno setting, which might explain the high figures?

This was on the old JB3 map 7 which was too much without an intercooler, even at the 5degC air temp on the day (freezing morning) the intake temp was right up at the end of each pull.

More like 400bhp with the more sensible map5 (i.e. same as JB4 map 5)

450ft/lb (616Nm) torque is more than a C63AMG V8!
