335is or an M3

I think COBB was a little late putting an IS specific tune together so published dynos might be a bit harder to find. FMIC will not do much to add to the cars power but it will help the car keep what power it does have.

Whaaa? Can't never put no power down -nor- go 'round no corner fer <$1k like M3. Can't even change no lane.

But.....fer maybe skosh more, can install meth....

BMW Performance Suspension can't never be real good 'cause:

• Progressive Springs
• Lacks LSD
• Oil filled rubber bushings
• Lower performance rear subframe bushings
• Spaghetti thin rear sway

Better then "Sport", not as good as a home made M3 suspension build, ultimately only as good as the driver in the end.

Did we ever find out if the 335IS has the rumored improved subframe bushings?
