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)
but can do E60's and other cars too.
Feel free to pm me anytime with any questions.
