Hey,
I am usually on the E90 forums however I recently found Maxbimmer which is more of a Canadian site.. thank god.. "some" Americans can be very rude.
I've been helping fellow GTA members code their cars.. if you need help pm me

for a code list.

I've coded: (2007-2012)
-E82 135i
-E82 128i
-E93 M3
-E92 M3
-E92 335
-E90 328
but can do E60's and other cars too.
Feel free to pm me anytime with any questions.
