911 enthusiast just bought M3 E30, Q about bosch DME upgrade

[kaotik]

hi

i was annoyed when pelican started the BMW section, i thought these were Porsche guys!!
well the subliminal approach worked, i bought a M3 E30 yesterday, it's a 87 195HP japan model

i read you can easily upgrade the 195 to a 215 hp, via a Bosch DME upgrade (as this was the original tune up)
The increased power is largely due to a reprogramming of the Bosch Digital Motor Electronics (DME).
BMW M Registry - FAQ E30 M3
can somebody confirm?
Bosch part number
quick fix?
downsides (can the clutch take it)

cheers
Kurt (still loyal to my 78 and 85 911
